&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Qual é o número positivo que elevado ao quadrado é igual 25? Basta pensar um pouco para descobrir que esse número é 5.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;5²= 5 · 5 = 25&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp;O número 5 é então chamado raiz quadrada de 25, e essa operação, chamada de radiciação, é representada assim:&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; Vejamos, agora, como representar a raiz quadrada exata de outros números. Utilizaremos o processo de fatoração para encontrar as raízes dos números dados.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;A origem e a formulação do conceito de Número ocorreu com o próprio desenvolvimento da Matemática. A partir das necessidades diárias do homem, o conceito de Número Natural surgiu naturalmente através da contagem de objetos. Assim, este conceito foi introduzido pelas nações, em conjunto com o desenvolvimento de suas formas próprias de escrita, criando o sistema de contagem.&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Os números negativos apareceram pela primeira vez, no decorrer da história da Matemática, na China Antiga, aproximadamente há 4000 anos. Os chineses realizavam cálculos através de duas coleções de barras, sendo a vermelha para números positivos e a preta para números negativos. Já os matemáticos indianos descobriram os números negativos quando tentavam formular um algoritmo de resolução para equações quadráticas.&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Com o início do Renascimento surgiu a expansão comercial, que aumentou a circulação de dinheiro, obrigando os comerciantes a expressarem situações envolvendo lucros e prejuízos. A maneira que eles encontraram de resolver tais situações problemas consistia no uso dos símbolos + e –. Suponha que um comerciante tenha três sacas de arroz de 10 kg cada em seu armazém. Se ele vendesse 5 Kg de arroz, escreveria o número 5 acompanhado do sinal –; se ele comprasse 7 Kg de arroz, escreveria o numeral 7 acompanhado do sinal +.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Utilizando essa nova simbologia, os Matemáticos da época desenvolveram técnicas operatórias capazes de expressar qualquer situação envolvendo números positivos e negativos. Surgia um novo conjunto numérico representado pela letra Z &lt;b&gt;(significa: Zahlen: número em alemão)&lt;/b&gt;, sendo formado pelos números positivos (Naturais) e seus respectivos opostos, podendo ser escrito da seguinte forma: &amp;nbsp;Z = {...,–3, –2, –1, 0, 1, 2, 3,...}&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;

&lt;span style=&quot;font-size: large;&quot;&gt;&lt;b&gt;- NÚMEROS INTEIROS.&amp;nbsp;&lt;/b&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;O conjunto dos números inteiros e composto pelo conjunto dos números naturais, que receberá o nome de conjuntos dos &lt;b&gt;&lt;u&gt;números inteiros positivos.&lt;/u&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Uma forma de representar geometricamente o conjunto Z é construir uma reta numerada, considerar o número 0 como a origem e o número 1 em algum lugar, tomar a unidade de medida como a distância entre 0 e 1 e por os números inteiros da seguinte maneira:&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Ao observar a reta numerada notamos que a ordem que os números inteiros obedecem é crescente da esquerda para a direita, razão pela qual indicamos com uma seta para a direita. Esta consideração é adotada por convenção, o que nos permite pensar que se fosse adotada outra forma, não haveria qualquer problema.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Baseando-se ainda na reta numerada podemos afirmar que todos os números inteiros possuem um e somente um antecessor e também um e somente um sucessor.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;O módulo ou valor absoluto de um número Inteiro é definido como sendo o maior valor (máximo) entre um número e seu elemento oposto e pode ser denotado pelo uso de duas barras verticais | &amp;nbsp;|. Assim:&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;

&lt;span style=&quot;white-space: pre;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;|x| = max {-x,x}&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;white-space: pre;&quot;&gt;Exemplos:
(a) |0| = 0
(b) |8| = 8
(c) |-6| = 6
&lt;/span&gt;&lt;span style=&quot;white-space: pre;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Observação: Do ponto de vista geométrico, o módulo de um número inteiro corresponde à distância deste número até a origem (zero) na reta numérica inteira.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-size: large; white-space: pre;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt; &lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Dois números são opostos quando têm &amp;nbsp;o mesmo módulo e sinais opostos, isto é, estão à mesma distância em relação à origem e em sentidos contrários.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;|-6|= 6 &amp;nbsp;Os números -6 e +6 são opostos ou simétricos. &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;|+6|= 6&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;|+2|= 2 Os números +2 e -2 também são opostos ou simétricos.&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;É o sinal menos que simboliza o oposto. O oposto de -2, que é +2, pode então ser escrito –(–2). Lê-se “o oposto de -2.&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;white-space: pre;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;b&gt;- COMPARAÇÃO DE NÚMEROS INTEIROS.&amp;nbsp;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;font-weight: bold;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Por meio da reta numérica também é possível comparar números inteiros. Para isso usamos os sinais &amp;gt; e &amp;lt;. Ao comparar dois números inteiros representados na reta numérica, o maior é o que estiver mais à direita.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Conta a história que o matemático Thomas Harriot criou os símbolos &amp;gt; e &amp;lt;. Eles são usados para substituir as palavras maior que ( &amp;gt; ) e menor que ( &amp;lt; ).&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;+6 é menor que +12 &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Por símbolos representamos assim: 6 &amp;lt; 12&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;-1 é maior que -5 &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Por símbolos representamos assim: -1 &amp;gt; -5&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Observações:&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;* Qualquer número positivo é sempre maior que qualquer número negativo.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;* Na comparação de dois números positivos, o maior deles é o que está mais distantes em relação a origem zero.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;* Ao comparar dois números negativos, &amp;nbsp;o maior deles é aquele mais próximo em relação à origem zero.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;
&lt;/span&gt;&lt;br /&gt;

A Matemática da música é mais um&amp;nbsp;vídeo&amp;nbsp;interessante da coleção matemática e arte. Este vídeo é um&amp;nbsp;documentário que mostra a relação entre os números e a música, fazendo uma viagem na historia e mostrando as ideias de grandes gênios, como&amp;nbsp;Pitágoras.&amp;nbsp;&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Tales de Mileto foi um importante filósofo, astrônomo e matemático grego que viveu antes de Cristo. Ele usou seus conhecimentos sobre Geometria e proporcionalidade para determinar a altura de uma pirâmide. Em seus estudos, Tales observou que os raios solares que chegavam à Terra estavam na posição inclinada e eram paralelos, dessa forma, ele concluiu que havia uma proporcionalidade entre as medidas da sombra e da altura dos objetos, observe a ilustração:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjY-rqp7pXPMYOxa79sIbDZjFi8xO9MFUGMErK-cLTIQWv4jar0WphLYVPaLvucn4GKbplhDJgn8J63WZioWee6i90vpRaGW6R654JExUPTRdldp_2-D3ff4KAFgyte8pkYo_b9O5-TkLLj/s1600/31193924.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;200&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjY-rqp7pXPMYOxa79sIbDZjFi8xO9MFUGMErK-cLTIQWv4jar0WphLYVPaLvucn4GKbplhDJgn8J63WZioWee6i90vpRaGW6R654JExUPTRdldp_2-D3ff4KAFgyte8pkYo_b9O5-TkLLj/s200/31193924.jpg&quot; width=&quot;156&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Com base nesse esquema, Tales conseguiu medir a altura de uma pirâmide com base no tamanho da sua sombra. Para tal situação ele procedeu da seguinte forma: fincou uma estaca na areia, mediu as sombras respectivas da pirâmide e da estaca em uma determinada hora do dia e estabeleceu a proporção:&lt;/span&gt;&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;O Teorema de Tales foi proposto para demonstrar que quando duas retas transversais (ou mais) cortam um feixe de retas paralelas, as medidas dos segmentos delimitados pelas transversais são proporcionais.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Vamos buscar uma melhor forma de entender esse assunto:&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Dadas as retas paralelas a, b e c, cortadas pelas retas a elas transversais r e s, tem-se:&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Pela proporcionalidade existente no Teorema, temos a seguinte situação:&lt;/span&gt;&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhXvifLt7I9UzzbZBm9k8CXcMDi4fd2xgnRyXpCkDZxImdyEAD052CZjuxwo8PJuIdlGCEAmOnnPXBeOoUM8yk6skGsWeB5uFPpRD22JrZeS2IbDeRiQ29L5Io3LhO3FDof0-AZo6qF0i1H/s1600/TALES.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhXvifLt7I9UzzbZBm9k8CXcMDi4fd2xgnRyXpCkDZxImdyEAD052CZjuxwo8PJuIdlGCEAmOnnPXBeOoUM8yk6skGsWeB5uFPpRD22JrZeS2IbDeRiQ29L5Io3LhO3FDof0-AZo6qF0i1H/s1600/TALES.jpg&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Vamos agora verificar um exemplo:&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Aplique o Teorema de Tales no intuito de determinar o valor de x, sabendo que as retas a, b e c são paralelas.&lt;/span&gt;&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Agora vamos a resposta:&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;De acordo com o Teorema de Tales temos:&lt;/span&gt;&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Logo, o valor de x de acordo com o Teorema de Tales é 7,5.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Razão e Proporção são conceitos diretamente &amp;nbsp;relacionados à grandeza.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;● Grandeza:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;– É uma relação numérica estabelecida com um objeto&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;– É tudo que se pode contar, medir, pesar, enfim,&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;enumerar.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;– Assim, a altura de uma árvore, o volume de um&amp;nbsp;tanque, o peso de um corpo, a quantidade pães,&amp;nbsp;entre outros, são grandezas.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif; font-size: x-large;&quot;&gt;Razão&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Em uma sala de aula de um certo&amp;nbsp;colégio tinha 25 meninos e 20 meninas.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Vamos comparar o número de meninos com o número de meninas!!!!!&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Uma maneira de comparar essa relação é calculando a&amp;nbsp;&lt;b&gt;razão &lt;/b&gt;entre o número de meninos e o&amp;nbsp;número&amp;nbsp;de meninas, mas devemos ficar atento a ordem considerada.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Assim, a razão pode ser expressa da seguinte forma:&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Podemos ler da seguinte forma a razão entre duas grandezas.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;/div&gt;

OBS: Para utilizar a calculadora corretamente, siga as seguintes instruções:&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
Ao utilizar algum numero com casa decimal, use ponto e não virgula. Pois o software só ler ponto.&lt;br /&gt;
&lt;b&gt;Ex: &amp;nbsp; &amp;nbsp; 35,45 deve ser digitado 35.45&lt;/b&gt;&lt;br /&gt;
&lt;b&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; 0,8 deve ser digitado 0.8&lt;/b&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;A palavra Trigonometria é formada por três radicais gregos: TRI = TRÊS, GONOS = ÂNGULOS e METRON = MEDIR. Considerada uma das áreas mais importantes da Matemática, pois possui diversas aplicações nos estudos relacionados à Física, Engenharia, Navegação Marítima e Aérea, Astronomia, Topografia, Cartografia, Agrimensura, entre muitas outras.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;A trigonometria possui uma infinidade de aplicações práticas. Desde a antiguidade já se usava da trigonometria para obter distâncias impossíveis de serem calculadas por métodos comuns.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Os estudos iniciais sobre a trigonometria são associados ao&amp;nbsp;matemático&amp;nbsp;grego Hiparco, ele &amp;nbsp;é considerado até hoje o pai &amp;nbsp;da trigonometria. Sendo isso, porque o mesmo foi o principal estudante sobre os assuntos iniciais da trigonometria. Este foi o que relacionou os lados e ângulos de um triângulo retângulo, e também possivelmente foi o primeiro a criar uma tabela de valores trigonométricos.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Os estudos trigonométricos no triângulo são embasados em três relações fundamentais: seno, cosseno e tangente.&lt;/span&gt;&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Dizemos &amp;nbsp;que a segunda rampa é mais íngreme ou tem aclive maior, pois seu ângulo de subida é maior (55º &amp;gt; 30º).&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Vejamos agora a seguinte &lt;b&gt;situação-problema&lt;/b&gt; sem conhecer os ângulos de subida, como saber qual das duas rampas é a mais íngreme???&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Para cada um dos pontos , a razão entre a altura e o afastamento correspondente é dada por:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9WQEuCCd_1ekaP7bY8IRBub6pJ9XIXBwGUWIaJh9ISnaGulr9tK4beq0hljcIHZ9YAD3E-nCbqiXlDrNEKIEZWvUgkskDE9PNc_NoUBtzi_ZWFyVCOpVHTzuTdx8MllrzzmzOXfoFciMK/s1600/Edi%C3%A7%C3%A3o_123.jpg&quot; imageanchor=&quot;1&quot; style=&quot;clear: left; float: left; margin-bottom: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;320&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9WQEuCCd_1ekaP7bY8IRBub6pJ9XIXBwGUWIaJh9ISnaGulr9tK4beq0hljcIHZ9YAD3E-nCbqiXlDrNEKIEZWvUgkskDE9PNc_NoUBtzi_ZWFyVCOpVHTzuTdx8MllrzzmzOXfoFciMK/s320/Edi%C3%A7%C3%A3o_123.jpg&quot; width=&quot;440&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Note que a razão entre a altura e o afastamento, para cada ponto de uma mesma subida, é uma constante (é sempre a mesma).&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Até agora, verificamos quanto &amp;nbsp;subida é íngreme usando o ângulo de subida ou então o índice de subida.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: left;&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;
&lt;li style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Quanto maior o ângulo de subida, mais íngreme é a subida.&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Quanto maior o índice de subida, mais íngreme é a subida.&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Será que podemos associar esses dois coeficientes numa mesma subida??&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;É o que veremos a seguir.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;b&gt;A idéia de tangente&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Usaremos a palavra &lt;i&gt;tangente&lt;/i&gt;&amp;nbsp;para associar a medida do ângulo de subida com o índice da mesma subida. A tangente do ângulo de subida é igual ao índice de subida associado, e o indicaremos por &lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;k1.&lt;/span&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Em qualquer subida podemos determinar a razão entre a altura e o percurso, que será um número que indicaremos por &lt;b style=&quot;font-size: x-large;&quot;&gt;k2. &lt;/b&gt;e chamaremos de seno do&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;font-family: Calibri, sans-serif; line-height: 115%;&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;ᾱ.&lt;/span&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;Para&amp;nbsp;prosseguimos&amp;nbsp;com nossos estudos é preciso que você já tenha estudado sobre semelhança de triângulos. Espero que você já tenha visto esse assunto pelo menos uma vez, pois fica difícil entender os&amp;nbsp;próximos&amp;nbsp;passos.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;Como você deve ter&amp;nbsp;percebido&amp;nbsp;os triângulos &lt;b&gt;OCD, OEF, OGH,&lt;/b&gt; etc., são semelhantes por terem os mesmos ângulos.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;Podemos portanto escrever:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Essa relação depende apenas do ângulo&amp;nbsp;&lt;/span&gt;θ &lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(e não do tamanho do triângulo retângulo do qual&amp;nbsp;&lt;/span&gt;θ &lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;é um dos ângulos agudos) e é chamado de &lt;b&gt;seno de&amp;nbsp;&lt;/b&gt;&lt;/span&gt;&lt;b&gt;θ &lt;/b&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;e escrevemos:&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

Os primeiros passos rumo às frações deram-se no Egito, pelas mãos do faraó&lt;b&gt; Sesóstris&lt;/b&gt;,
que teve a ideia de repartir as terras próximas ao Rio Nilo para alguns
agricultores. Mas na época de cheia do Nilo a divisória entre o terreno
de cada um era perdida, então esses agricultores passaram a marcar uma 
corda com números fracionados, já que dificilmente um pedaço de terra 
tinha uma medida inteira, serviço praticado pelos estiradores de cordas.
 Por exemplo: a corda era estirada ao todo três vezes e meia para 
abranger todo o terreno.&lt;br /&gt;
&lt;br /&gt;
&lt;a name=&#39;more&#39;&gt;&lt;/a&gt;&lt;/div&gt;

&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
&lt;br /&gt;
A matemática com o uso das frações foi se desenvolver anos mais tardes. Os egípcios consideravam a fração como fazendo parte da unidade. No Egito por volta de 1.650 a.C., já existia uma espécie de manual de matemática conhecido como papiro Ahmes, continha 80 problemas de matemática e suas resoluções. Envolviam situações como calcular preço de pão, grãos, alimentação do gado, ou seja, atribulações diárias do cotidiano daquele povo. Sendo o sistema de números dos egípcios baseado em sete números chave.&lt;br /&gt;
&lt;br /&gt;
Posteriormente as frações foram sendo utilizadas por outros povos, de outras maneiras, como em Roma e na Síria. Os gregos também foram povos doutos de muito saber. Entretanto, foi o sistema de numeração hindu que revolucionou o que conhecemos hoje por números racionais, o que simplificou e muito os cálculos com frações.&lt;/div&gt;
&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
&lt;b style=&quot;color: #0b5394;&quot;&gt;As frações surgiram da nescessidade de registrar as medidas de forma mais precisa.&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
&lt;b&gt;Fração&lt;/b&gt; é um modo de expressar uma quantidade a partir de um valor que &lt;b&gt;é dividido por um determinado número de partes iguais entre si.&lt;/b&gt; A palavra vem do latim fractus e significa &quot;partido&quot;, &quot;quebrado&quot; (do verbo frangere: &quot;quebrar&quot;).&lt;/div&gt;
&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;font-family: Arial,Helvetica,sans-serif; text-align: justify;&quot;&gt;
Vamos imaginar a seguinte situação :&lt;br /&gt;
&lt;br /&gt;
Samuel comprou uma pizza e dividiu para seus dois amigos Anderson e Márcio, de modo que ficassem três partes iguais. &lt;br /&gt;
&lt;br /&gt;
Que parte caberá a cada um?&lt;br /&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;São aquelas em que o numerador é multiplo do denominador.&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Esta fração é aparente pois 10(numerador) é multiplo de 5(denominador).&lt;/span&gt;&lt;br /&gt;

&lt;/ul&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Podemos comparar frações utilizando a representação numérica através de algumas técnicas e propriedades.&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Comparar duas frações significa estabelecer uma relação de igualdade ou desigualdade entre elas.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Quando os denominadores são iguais, basta compararmos somente o valor dos numeradores.&amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

Como 5 &amp;gt; 3 &amp;gt; 1, logo a maior fração será aquela com o numerador 5.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
A fração 5/8 é maior que 3/8 que é maior que 1/8. Como posso ter certeza?&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
É simples. Toda fração é uma divisão, portanto, basta dividirmos o numerador pelo&amp;nbsp;denominador. A fração que apresentar o resultado maior será a maior!&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
5/8 = 0,625 ; 3/8 = 0,375 ; 1/8 = 0,125&lt;/div&gt;
&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Outra maneira de raciocinarmos seria&amp;nbsp;entender que dividir 5 laranjas entre 8 pessoas será um número &lt;b&gt;MAIOR&lt;/b&gt; de&amp;nbsp;laranjas (neste caso pedaço de laranja) do que dividir 3 laranjas entre 8 pessoas e&amp;nbsp;assim sucessivamente...&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Quando os denominadores são diferentes, devemos realizar operações no intuito dos denominadores se tornarem iguais. Quando eles se tornam iguais aplicamos as definições da primeira situação. &amp;nbsp;O processo que irá transformar os denominadores em valores iguais é chamado de redução e consiste em descobrir um número pelo qual iremos multiplicar os membros de uma fração para que os denominadores assumam o mesmo valor. Observe:&amp;nbsp;&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;As frações dadas possuem denominador 2, 3 e 4. &amp;nbsp;Devemos encontrar o menor multiplico comum entre elas. Para isso, podemos fatorar os denominadores.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Utilizaremos o 12 como denominador comum entre elas.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Em seguida, dividimos o numero doze pelo antigo denominador e multiplicamos o resultado pelo numerador. Como mostra a operação abaixo.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;12/2 = 6 &amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;12/3 = 4&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;12/4 = 3&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;As frações 2/3, 4/6 e 6/9 representam o mesmo valor, porém seus termos são números diferentes. Estas frações são denominadas Frações Equivalentes.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Para obtermos uma fração equivalente a outra, basta multiplicar ou dividir o numerador e o denominador pelo mesmo número (diferente de zero).&lt;/span&gt;&lt;br /&gt;

mmc (2,3) = 6&lt;br /&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
O MMC entre 4 e 3 é o 12 , sabemos disso pois o 6 é o menor número que pode ser dividido pelos dois denominadores (4,3).&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
O próximo passo é dividir o MMC achado, neste caso o 6 pelo denominador de cada fração e&amp;nbsp;multiplicar&amp;nbsp;o resultado da divisão pelo numerador.&amp;nbsp;&lt;/div&gt;

&lt;/ul&gt;
&lt;br /&gt;
&lt;b&gt;Observe o problema.&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
Suzana ganhou 1/2&amp;nbsp;de uma barra de chocolate. Ela resolveu dividir o que ganhou com sua &amp;nbsp;amiga, em partes iguais. Com que fração da barra de chocolate cada uma delas ficou?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Para realizarmos a divisão de frações, devemos transformar a divisão em multiplicação. Na divisão de números fracionários, devemos multiplicar a primeira fração pelo inverso da &amp;nbsp;segunda.
&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;Exemplo:&lt;/b&gt;&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgwag_xY8djBKJOlD_Gc-tSuk0JTSUX0efaH84RJ9ydM6equOr0NVKnXVIFM7HOeTdYsjbN6hhdUd0WRQkCmR6m-w8qo9YQLuz_OHS6OJr-t7hw_Sz4Rn51s2EJvPWF15oXQoaQ2VG-Arff/s1600/exemplo+17.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;168&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgwag_xY8djBKJOlD_Gc-tSuk0JTSUX0efaH84RJ9ydM6equOr0NVKnXVIFM7HOeTdYsjbN6hhdUd0WRQkCmR6m-w8qo9YQLuz_OHS6OJr-t7hw_Sz4Rn51s2EJvPWF15oXQoaQ2VG-Arff/s400/exemplo+17.jpg&quot; width=&quot;400&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;
&lt;b&gt;&lt;br /&gt;&lt;/b&gt;
Bem, por esse&amp;nbsp;método&amp;nbsp;fica simples a resolução do problema acima.&lt;br /&gt;
&lt;br /&gt;
Então vamos lá!!!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;Problema.&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
Suzana ganhou 1/2&amp;nbsp;de uma barra de chocolate. Ela resolveu dividir o que ganhou com sua &amp;nbsp;amiga, em partes iguais. Com que fração da barra de chocolate cada uma delas ficou?&lt;br /&gt;
&lt;br /&gt;
Suzane possui metade de uma barra de chocolate. Mas, como ela resolveu dividir a metade da barra &amp;nbsp;com sua amiga, logo ela ficou com a metade da&amp;nbsp;metade da barra de chocolate.&lt;br /&gt;
&lt;br /&gt;
Confuso não é?&lt;br /&gt;
&lt;br /&gt;
Vamos escrever essa operação matematicamente.&lt;br /&gt;
Ela&amp;nbsp;possuía 1/2 da barra de chocolate, então ela dividiu esse 1/2 para 2. Como mostra a figura abaixo.&lt;br /&gt;
&lt;br /&gt;

Dividiu sua metade por 2.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
Logo, ela ficou com 1/4 da barra de chocolate.&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(a) 1 não é primo pois D(1)={1}&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(b) 2 é primo pois D(2)={1,2}&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(c) 3 é primo pois D(3)={1,3}&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(d) 5 é primo pois D(5)={1,5}&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(e) 7 é primo pois D(7)={1,7}&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(f) 14 não é primo pois D(14)={1,2,7,14}&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Observação: 1 não é primo pois tem apenas 1 divisor e todo número natural pode ser escrito como o produto de números primos, de forma única.&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/b&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-size: x-large;&quot;&gt;Crivo de Eratóstenes&lt;/span&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;text-align: left;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;text-align: left;&quot;&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;Eratóstenes foi um sábio grego, dos séculos II e III a.C., que desenvolveu um método para encontrar números primos. Esse processo é utilizado para obter números primos menores do que um determinado número natural n. Devemos construir uma tabela contendo os primeiros n números naturais. Para determinar os números primos nesta tabela, basta seguir os seguintes passos.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;1 - Antes de iniciar, lembramos que 1 não é um número primo.&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;2 - Marcamos o número 2, que é o primeiro número primo e eliminamos todos os múltiplos de 2 que encontrarmos na tabela.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;3 - Marcamos o número 3 e eliminamos todos os múltiplos de 3 que encontrarmos na tabela.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;4 - Determinamos o próximo número primo, que será o próximo número não marcado da tabela e eliminamos todos os múltiplos desse número primo que encontrarmos na tabela.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;5 - Continuamos o processo, sempre voltando ao passo anterior, com o próximo número primo.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;6 - Os números que não foram eliminados são os números primos.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;display: inline !important;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;display: inline !important;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;b&gt;&lt;/b&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;display: inline !important;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;b&gt;Vamos seguir os passos indicados acima &amp;nbsp;para obter todos os números primos até 120:&lt;/b&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;1 - &amp;nbsp;Reforçando novamente que o número 1 já está riscado, visto não ser primo.&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;2 - Desenha um círculo à volta do 2, visto ser primo, e risca os restantes múltiplos de 2;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;3 - Desenha um círculo à volta do 3, visto ser primo, e risca os restantes múltiplos de 3;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;4 - Desenha um círculo à volta do 5, visto ser primo, e risca os restantes múltiplos de 5;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;6 - Desenha um círculo à volta do 7, visto ser primo, e risca os restantes múltiplos de 7;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;8 - Desenha um círculo à volta de todos os números que ainda não estão riscados, pois eles são números primos.&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;i&gt;Agora vamos ver isso&amp;nbsp;acontecendo&amp;nbsp;na tabela abaixo:&lt;/i&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-size: large;&quot;&gt;&lt;b&gt;2 é divisor de 8, pois 8=2×4, logo 8 é múltiplo de 2 e também é múltiplo de 4.&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Exemplos:&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(1) Divisores de &amp;nbsp;8: D(8)={1,2,4,8}&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(2) Divisores de 16: D(16)={1,2,4,8,16}&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(3) Divisores de 20: D(20)={1,2,4,5,10,20}&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Observação:&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Se aplicarmos essa definição no conjunto dos numero naturais incluindo o 0(zero), o número zero se tornaria múltiplo de todos os números naturais, mais zero não divide qualquer número natural, exceto ele próprio.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Vamos Entender melhor:&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Se aceitarmos que&lt;b&gt; 6÷0=b&lt;/b&gt;, então teremos que admitir que:&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;6 = 0 x b&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Mas não existe um número &lt;b&gt;b&lt;/b&gt; que multiplicado por 0 (zero) seja igual a 6, portanto a divisão de 6 por 0 é impossível.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;A divisão de 0/0 (zero por zero) é indeterminada, o que significa que pode existir uma situação que ela passe a ter significado, no sentido seguinte:&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Se aceitarmos que 0÷0=X, então poderemos escrever que:&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;0 ÷ 0 = X ÷ 1&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Como temos uma igualdade de frações, gerando uma proporção, deveremos aceitar que o produto dos meios é igual ao produto dos extremos nesta proporção e assim:&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;0 × 1 = 0 × X = 0&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;que não é contraditório e isto pode ser realizado para todo X real, razão pela qual a expressão da forma 0÷0 é dita indeterminada.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-size: x-large;&quot;&gt;Critérios de divisibilidade&lt;/span&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;Para alguns números como o dois, o três, o cinco e outros, existem regras que permitem verificar a divisibilidade sem se efetuar a divisão. Essas regras são chamadas de critérios de divisibilidade.&lt;/span&gt;&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Um número natural é divisível por 2 quando ele termina em 0, ou 2, ou 4, ou 6, ou 8, ou seja, quando ele é par.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Exemplos:&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;1) 5040 é divisível por 2, pois termina em 0.&lt;/span&gt;&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Um número é divisível por 11 quando a diferença entre as somas dos valores absolutos dos algarismos de ordem ímpar e a dos de ordem par é divisível por 11.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;O algarismo das unidades é de 1ª ordem, o das dezenas de 2ª ordem, o das centenas de 3ª ordem, e assim sucessivamente.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; Como a subtração não pode ser realizada, acrescenta-se o menor múltiplo de 11 (diferente de zero) ao minuendo, para que a subtração possa ser realizada: 10+11 = 21.

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; Como zero é divisível por 11, o número 439087 é divisível por 11.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;

Hoje conversando com um de meus amigos o Thiago (&amp;nbsp;&lt;a href=&quot;https://www.facebook.com/thiago.laurindo.52&quot;&gt;https://www.facebook.com/thiago.laurindo.52&lt;/a&gt;&amp;nbsp;). O mesmo me solicitou alguns jogos das quatros operações básicas. Sei que nosso foco é ensino fundamental, mais multiplicação sempre é bem vinda... &amp;nbsp;:)&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Nesse jogo você terá que acerta as contas que apareceram na tela, para que seu&amp;nbsp;personagem&amp;nbsp;possa&amp;nbsp;ultrapassar&amp;nbsp;os&amp;nbsp;obstáculos. Bem divertido e de grande&amp;nbsp;importância&amp;nbsp;pra galera que tem certa&amp;nbsp;dificuldade&amp;nbsp;em multiplicar..&lt;/div&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Exemplos:&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(?)&lt;b&gt;&amp;nbsp; &amp;nbsp;a &lt;/b&gt;é múltiplo de&lt;b&gt; b&lt;/b&gt;, pois&amp;nbsp;&lt;b&gt; a= b x K&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(a) 15 é múltiplo de 5, pois 15=3×5.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(b) 24 é múltiplo de 4, pois 24=6×4.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(c) 24 é múltiplo de 6, pois 24=4×6.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;(d) 27 é múltiplo de 9, pois 27=3×9.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: left;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;Se &lt;span style=&quot;font-size: large;&quot;&gt;&lt;b&gt;a=k×b&lt;/b&gt;&lt;/span&gt;, então &lt;span style=&quot;font-size: large;&quot;&gt;&lt;b&gt;a&lt;/b&gt; &lt;/span&gt;é múltiplo de &lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;b&lt;/span&gt;&lt;/b&gt;, mas também, &lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;a&lt;/span&gt;&lt;/b&gt; é múltiplo de &lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;k&lt;/span&gt;&lt;/b&gt;, como é o caso do número 35 que é múltiplo de 5 e de 7, pois:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;35=7×5&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: left;&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp;Se &lt;b&gt;&lt;span style=&quot;font-size: large;&quot;&gt;a=k×b&lt;/span&gt;&lt;/b&gt;, então &lt;span style=&quot;font-size: large;&quot;&gt;a&lt;/span&gt; é múltiplo de &lt;span style=&quot;font-size: large;&quot;&gt;b&lt;/span&gt; e se conhecemos &lt;span style=&quot;font-size: large;&quot;&gt;b&lt;/span&gt; e queremos obter todos os seus múltiplos, basta fazer &lt;span style=&quot;font-size: large;&quot;&gt;k&lt;/span&gt; assumir todos os números naturais possíveis.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Por exemplo:&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Para obter todos os múltiplos de 2, isto é, os números da forma &lt;b&gt;a=k×2&lt;/b&gt; onde &lt;b&gt;k&lt;/b&gt; é substituído por todos os números naturais possíveis. A tabela abaixo nos auxiliará:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;a=k x 2&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;0=0×2&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;2=1×2&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;4=2×2&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;6=3×2&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;8=4×2&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;10=5×2&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;12=6×2..........&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Observação: Como estamos considerando 0 como um número natural, então o zero será múltiplo de todo número natural. Tomando &lt;b&gt;k=0&lt;/b&gt; em &lt;b&gt;a=k.b&lt;/b&gt; obtemos &lt;b&gt;a=0&lt;/b&gt; para todo &lt;b&gt;b&lt;/b&gt; natural. Por exemplo:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;0=0×2, &amp;nbsp;0=0×5, &amp;nbsp;0=0×12, &amp;nbsp;0=0×15&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Observação: Um número &lt;b&gt;b&lt;/b&gt; é múltiplo dele mesmo.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;a = 1 × b&lt;/b&gt; &amp;nbsp; se, e somente se, &amp;nbsp; &amp;nbsp;&lt;b&gt;a = b&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Por exemplo:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Vamos multiplicar o mesmo número por 1 para obter um múltiplo dele próprio, como:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;3=1x3&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;5=1x5&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;15=1x15.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Vamos agora aplicar esse conceito em um exemplo prático:&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; Em uma escola será realizado uma gincana para a qual estão escritos 108 alunos. Se forem formadas equipes de 6 alunos cada, algum aluno ficará de fora????&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Ai você me pergunta, vai ou não vai???&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; &amp;nbsp; Bom, para resolver essa questão, precisamos saber se 108 : 6 é uma divisão exata (resto =0) ou uma divisão não exata (resto&amp;nbsp;≠&lt;/span&gt;&lt;span style=&quot;font-family: sans-serif; font-size: x-small;&quot;&gt;&lt;span style=&quot;line-height: 19.200000762939453px;&quot;&gt;&lt;b&gt;&amp;nbsp;&lt;/b&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;0).&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;veja:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Como a divisão é exata, podemos afirmar que:&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; font-weight: bold;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp; * 108 É DIVISÍVEL POR 6&lt;/b&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; text-align: center;&quot;&gt;&amp;nbsp; * 108 É MÚLTIPLO DE 6&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;div style=&quot;text-align: right;&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; text-align: center;&quot;&gt;
&lt;/span&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; text-align: center;&quot;&gt;&lt;/span&gt;&lt;/b&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; text-align: center;&quot;&gt;&amp;nbsp; * &amp;nbsp;6 É DIVISOR DE 108&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;/div&gt;
&lt;b&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif; text-align: center;&quot;&gt;
&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Então, se forem formadas equipes de 6 alunos, não sobrará aluno. Assim a&amp;nbsp;brincadeira&amp;nbsp;pode acontecer numa boa, sem imprevistos.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Observe que o mesmo não acontece se cada equipe tiver 5 alunos&lt;i&gt;.&lt;/i&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: right;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;Como 108 : 5 não é divisão exata, dizemos que:&lt;/b&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;* 108 não é divisível por 5&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;* 108 não é múltiplo de 5&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;b&gt;* &amp;nbsp;5 &amp;nbsp; &amp;nbsp;não é divisor de 108&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Dessa forma, se forem formadas equipes de 5 alunos, sobrarão 3 alunos.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: left;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
