Question

( -3/5) + (-1/2) . (+4) : (-2)

Answer 1

Resposta:

$\frac{8}{5}$

Explicação passo-a-passo:

$\frac{-3}{5} + ( - \frac{1}{2} ).( + 4) \div ( - 2) = \frac{-3}{5} - \frac{4}{2} \div - 2 = \frac{-3}{5} - \frac{4}{2} \times - \frac{1}{2} = \frac{-3}{5} + \frac{4}{4} = \frac{-3}{5} + 1 =$

$mmc = 5$

$\frac{-3 + 5}{5} = \frac{2}{5}$
