2/5 : 3/7 =
1/5 : 1/10 =
3/2 : 5/4=

Answer 1

Resposta:

$\frac{2}{5} \div \frac{3}{7} = \frac{2}{5} \times \frac{7}{ 3} = \frac{14}{15} \\ \\ \frac{1}{5} \div \frac{1}{10} = \frac{1}{5} \times 10 = 2 \\ \\ \frac{3}{2} \div \frac{5}{4} = \frac{3}{2} \times \frac{4}{5} = 3 \times\frac{2}{5} = \frac{6}{5}$
