Answer 1

Explicação passo-a-passo:

$1)a- \frac{5.6}{2} \\ - 5.3 \\ = - 15 \\ b) \frac{9.8}{2} \\ 9.4 \\ = 36 \\ 2)a \: - \frac{2.6.3}{9.2} \\ - \frac{6.3}{9} \\ - \frac{6}{3} \\ = - 2$

$b \: - \frac{6.2.3}{9} \\ - \frac{6.2}{3} \\ - 2.2 \\ = - 4$

$c \: - \frac{6.4.5}{3.8} \\ - \frac{2.5}{2} \\ = - 5 \\ d \: - \frac{2.3.4}{3.8} \\ - \frac{4}{4} \\ = - 1$

$3)a \: \frac{0}{30} \\ = 0 \\ b \: \frac{7.8}{14} \\ \frac{8}{2} \\ = 4 \\ c \: \frac{ - 19}{19} \\ = - 1$

$d \: \frac{10 + 5}{9 - 7 + 1} \\ \frac{10 + 5}{3} \\ \frac{15}{3} \\ = 5 \\ e \: \frac{ - 30 - 40}{5.( - 2)} \\ \frac{ - 70}{5.( - 2)} \\ \frac{14}{2} \\ = 7$

$f \: \frac{3 + 2}{7 - 8} \\ \frac{3 + 2}{ - 1} \\ \frac{5}{ - 1} \\ = - 5$
