Answer 1

Resposta:

$\frac{7}{12}\div \frac{2}{8}\\\\\mathrm{Aplicar\:as\:propriedades\:das\:fracoes}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}\\\\\frac{7}{12}\times \frac{8}{2}\\\\\frac{7}{3}\times \frac{2}{2}\\\\\mathrm{Multiplicar\:fracoes}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}\\\\\frac{7\times \:2}{3\times \:2}\\\\\mathrm{Eliminar\:o\:fator\:comum:}\:2\\\\\frac{7}{3}$
