Answer 1

Resposta:

$\frac{9}{4}$

Explicação passo-a-passo:

$( \frac{2}{1} \times ( - \frac{3 }{4} ) \div ( - \frac{2}{3} )) \\ \\ - \frac{2 \times 3}{1 \times 4} \div ( - \frac{2}{3} ) \\ \\ - \frac{6}{4} \div ( - \frac{2}{3} ) \\ \\ - \frac{3}{2} \div ( - \frac{2}{3} ) \\ \\ - \frac{3}{2} \times ( - \frac{3}{2} ) = \frac{9}{4}$
