$\frac{2}{5} \times \frac{1}{3}$
$\frac{3}{4} \times \frac{5}{3}$
$\frac{2}{3} \times \frac{4}{5}$
​

Answer 1

Explicação passo-a-passo:

$\frac{2}{5} \times \frac{1}{3} = \frac{2 \times 1}{5 \times 3} = \frac{2}{15}$

$\frac{3}{4} \times \frac{5}{3} = \frac{3 \times 5}{4 \times 3} = \frac{15}{12} = \div \frac{3}{3} = \frac{5}{4}$

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