Question

$(8) \times ( - \frac{1}{4} ) \times ( \frac{21}{8} ) \times ( - \frac{3}{7} \times ( - \frac{2}{3} ) =$

Answer 1

$(8) \times ( - \frac{1}{4} ) \times ( \frac{21}{4} ) \times ( - \frac{3}{7} ) \times ( - \frac{2}{3}$
$- 8 \times \frac{1}{4} \times \frac{21}{8} \times \frac{3}{7} \times \frac{2}{3}$
$- \frac{1}{4} \times 21 \times \frac{1}{7} \times 2$
$- \frac{1}{4} \times 3 \times 2$
$- \frac{1}{2} \times 3$
$- \frac{3}{2} = - 1.5$
