​

Answer 1

Resposta:

12/125

Explicação passo-a-passo:

$( - \frac{3}{5}) \div ( - \frac{5}{4}) \div 5 \\ \frac{3}{5} \div \frac{5}{4} \div 5 \\ \frac{3}{5} \times \frac{4}{5} \div 5 \\ \frac{3}{5} \times \frac{4}{5} \times \frac{1}{5} \\ \frac{3 \times 4 \times 1}{5 \times 5 \times 5} = \frac{12}{5 \times 5 \times 5} = \frac{12}{125}$
