Explicação passo a passo:

Answer 2

Resposta:

$\purple{a)} \red{1} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \purple{b)} \red{ \frac{2}{9}}$

Explicação passo-a-passo:

$\blue{a)\frac{3}{2} \times \frac{2}{3}} \\ \\ \frac{3}{2} \times \frac{2}{3} \\ \\ \frac{1}{2} \times \frac{2}{1} \\ \\ \frac{1}{1} \times \frac{1}{1} \\ \\ \frac{3}{2} \times \frac{2}{3} \\ \\ \frac{1}{1} \times \frac{1}{1} \\ \\ \frac{1 \times 1}{1 \times 1} \\ \\ \frac{1}{1 \times 1} \\ \\ \frac{1}{1} \\ \\ 1 \\ \green{resposta} \\ \red{1} \\ \\ \blue{b) \frac{1}{3} \times \frac{4}{6}} \\ \\ \frac{1}{3} \times \frac{4}{6} \\ \\ \frac{1}{3} \times \frac{2}{3} \\ \\ \frac{1}{3} \times \frac{4}{6} \\ \\ \frac{1}{3} \times \frac{2}{3} \\ \\ \frac{1 \times 2}{3 \times 3} \\ \\ \frac{2}{3 \times 3} \\ \\ \frac{2}{9} \\ \green{resposta} \\ \red{ \frac{2}{9}}$
