Answer 1

Explicação passo-a-passo:

.

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

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

$- \dfrac{4}{12}$

$- \dfrac{4 {}^{ \div 4} }{12 {}^{ \div 4} }$

$- \dfrac{1}{3}$

.

$b) - 3 \div - \dfrac{3}{2}$

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

$\dfrac{6}{3}$

$2$

.

$c) \dfrac{1}{4} \div - \dfrac{6}{2}$

$\dfrac{1}{4} \times - \dfrac{2}{6}$

$- \dfrac{2 }{24}$

$- \dfrac{2 {}^{ \div 2} }{24 {}^{ \div 2} }$

$- \dfrac{1}{12}$

.

$\dfrac{12}{7} \div - \dfrac{1}{4}$

$\dfrac{12}{7} \times - \dfrac{4}{1}$

$- \dfrac{48}{7}$
