Answer 1

Explicação passo-a-passo:

a)

$a) \frac{3}{4} \div \frac{7}{3} = \frac{3}{4} \times \frac{3}{7} = \frac{9}{28} \\ \\ b) \frac{4}{1} \div \frac{3}{8} = \frac{4}{1} \times \frac{8}{3} = \frac{32}{3} \\ \\ c) \frac{6}{5} \div \frac{1}{8} = \frac{6}{5} \times \frac{8}{1} = \frac{48}{5} \\ \\ d) \frac{12}{7} \div \frac{1}{3} = \frac{12}{7} \times \frac{3}{1} = \frac{36}{7}$
