Answer 1

Explicação passo-a-passo:

$\boxed{{\begin{array}{}a) \: \frac{4}{8} \div \frac{2}{2} = \frac{2}{4} \div \frac{2}{2} = \frac{1}{2} \\ \\ b) \: \frac{20}{30} \div \frac{2}{2} = \frac{10}{15} \div \frac{5}{5} = \frac{2}{3} \\ \\ c) \: \frac{12}{4} \div \frac{2}{2} = \frac{6}{2} \div \frac{2}{2} = \frac{3}{1} \\ \\ d) \: \frac{6}{12} \div \frac{2}{2} = \frac{3}{6} \div \frac{3}{3} = \frac{1}{2} \\ \\ e) \: \frac{3}{9} \div \frac{3}{3} = \frac{1}{3} \\ \\ f) \: \frac{8}{12} \div \frac{4}{4} = \frac{2}{3} \\ \\ g) \: \frac{50}{100} \div \frac{5}{5} = \frac{10}{20} \div \frac{5}{5} = \frac{2}{4} \div \frac{2}{2} = \frac{1}{2} \\ \\ h) \: \frac{3}{18} \div \frac{3}{3} = \frac{1}{6} \end{array}}}$
