me ajudem por favor!!!!!​

Answer 1

Resposta:

Explicação passo-a-passo:

a)$\left(\frac{-4}{6}\right)\left(\frac{5}{3}\right)$

$\left(\frac{-4}{6}\right)\left(\frac{5}{3}\right)=\\\\-\frac{4}{6}\times \frac{5}{3}=\\\\-\frac{2\times \:2}{6}\times \frac{5}{3}=\\\\-\frac{2\times \:2}{2\times \:3}\times \frac{5}{3}=\\\\-\frac{2}{3}\times \frac{5}{3}=\\\\-\frac{2\times \:5}{3\times \:3}=\\\\-\frac{10}{3\times \:3}=\\\\=-\frac{10}{9}$

b) $\left(\frac{-5}{6}\right)\div \left(\frac{4}{3}\right)\:\:$

$\left(\frac{-5}{6}\right)\div \left(\frac{4}{3}\right)\:\:=\\\\=\frac{-\frac{5}{6}}{\frac{4}{3}}\\\\=-\frac{\frac{5}{6}}{\frac{4}{3}}\\\\=-\frac{5\cdot \:3}{6\cdot \:4}\\\\=-\frac{5\cdot \:3}{24}\\\\=-\frac{15}{24}\\\\=-\frac{5}{8}$
