Answer 1

Resposta:

$\frac{3}{9} \div \frac{4}{8} = \frac{3}{9} \times \frac{8}{4} = \frac{24}{36} = \frac{12}{18} = \frac{6}{9} = \frac{2}{3}$

$\frac{6}{7} \div \frac{5}{3} = \frac{6}{7} \times \frac{3}{5} = \frac{18}{35}$

$\frac{2}{5} \div \frac{8}{15} = \frac{2}{5} \times \frac{15}{8} = \frac{30}{40} = \frac{3}{4}$
