Question

(+8/5):(-4) -6 .(-1/4)

Answer 1

Explicação passo-a-passo:

$\frac{8}{5} \div ( - 4) - 6 \times ( - \frac{1}{4} ) = \\ \\ \frac{8}{5} \times ( - \frac{1}{4} ) + \frac{6}{4} = \\ \\ - \frac{8}{20} + \frac{3}{2} = \\ \\ - \frac{2}{5} + \frac{3}{2} = \\ \\ \frac{ - (2 \times 2) + (5 \times 3)}{5 \times 2} = \\ \\ \frac{ - 4 + 15}{10} = \\ \\ \frac{11}{10}$
