Answer 1

Resposta:

k)

$\frac{117}{5}$

L)

$\frac{14}{15}$

Explicação passo-a-passo:

k)

$( - \frac{3}{5} ) + ( - 12) \times 4 \div ( - 2) \\ - \frac{3}{5} + 24 \\ \frac{117}{5}$

l)

$( - \frac{7}{11}) \times ( - \frac{1}{3} \times \frac{22}{5}) \\ ( - \frac{7}{11} ) \times ( - \frac{22}{15} ) \\ 7 \times \frac{2}{15} \\ \frac{14}{15}$
