Answer 1

Resposta:

$a) \frac{2}{4} \div \frac{1}{3} = \frac{2}{4} \times \frac{3}{1} = \frac{6}{4} \\ \\ b) \frac{10}{21} \div \frac{2}{5} = \frac{10}{21} \times \frac{5}{2} = \frac{50}{42} \\ \\ c) \frac{7}{8} \div \frac{3}{6} = \frac{7}{8} \times \frac{6}{3} = \frac{42}{24} \\ \\ d) \frac{3}{6} \div \frac{5}{8} = \frac{3}{6} \times \frac{8}{5} = \frac{24}{30} \\ \\ e) \frac{3}{5} \div \frac{4}{8} = \frac{3}{5} \times \frac{8}{4} = \frac{24}{20} \\ \\ f) \frac{6}{8} \div \frac{2}{3} = \frac{6}{8} \times \frac{3}{2} = \frac{18}{16}$
