Answer 1

Explicação passo-a-passo:

.

$5 \div - \dfrac{3}{2}$

$5 \times - \dfrac{2}{3}$

$- \dfrac{10}{3}$

.

$- 4 \div - \dfrac{3}{5}$

$- 4 \times - \dfrac{5}{3}$

$\dfrac{20}{3}$

.

$- 3 \div - \dfrac{2}{9}$

$- 3 \times - \dfrac{9}{2}$

$\dfrac{27}{2}$

.

$- \dfrac{5}{2} \div 2$

$- \dfrac{5}{2} \times \dfrac{1}{2}$

$- \dfrac{5}{4}$

.

$\dfrac{4}{3} \div - 2$

$\dfrac{4}{ 3} \times - \dfrac{1}{2}$

$- \dfrac{4 \div 2}{6 \div 2}$

$- \dfrac{2}{3}$

.

$- \dfrac{3}{5} \div 0.1$

$- \dfrac{3}{5} \div \dfrac{1}{10}$

$- \dfrac{3}{5} \times \dfrac{10}{1}$

$- \dfrac{30}{5}$

$- 6$
