Answer 1

Resposta:

$a)\frac{15}{16} \: \: \: \: \: \: b) \frac{1}{6} \: \: \: \: \: \: c) \frac{1}{4} \: \: \: \: \: \: d) \frac{5}{3}$

Explicação passo-a-passo:

$a) \: \frac{3}{8} \div \frac{2}{5} = \frac{3}{8} \times \frac{5}{2} = \frac{15}{16} \\ \\ b) \frac{1}{4} \div \frac{3}{2} = \frac{1}{4} \times \frac{2}{3} = \frac{2}{12} = \frac{1}{6} \\ \\ c) \frac{3}{8} \div \frac{9}{6} = \frac{3}{8} \times \frac{6}{9} = \frac{18}{72} = \frac{9}{36} = \frac{1}{4} \\ \\ d) \: \frac{5}{6} \div \frac{1}{2} = \frac{5}{6} \times \frac{2}{1} = \frac{10}{6} = \frac{5}{3}$
