Answer 1

Resposta:

$-\frac{7}{8}$

Explicação passo a passo:

$-\frac{3}{4} -1=-\frac{3}{4}-\frac{4}{4} =-\frac{7}{4}$

  $\frac{3}{2} -1=\frac{3}{2}-\frac{2}{2}=\frac{1}{2}$

 $(-\frac{7}{4})\:.\:(\frac{1}{2}) =-\frac{7}{8}$

Answer 2

$( - \frac{3}{4} - \frac{1}{1} ) \times ( \frac{3}{2} - \frac{1}{1} ) \\ ( - \frac{3}{4} - \frac{4}{4} ) \times ( \frac{3}{2} - \frac{2}{2} ) \\ - \frac{7}{4} \times \frac{1}{2} = - \frac{7}{8}$
