Find $\frac{-4}{5} \times \frac{3}{7} \times \frac{15}{16} \times\left(\frac{-14}{9}\right)$

Answer

We have, $\frac{-4}{5} \times \frac{3}{7} \times \frac{15}{16} \times\left(\frac{-14}{9}\right)$
$=\left(\frac{-4}{5} \times \frac{15}{16}\right) \times\left[\frac{3}{7} \times\left(\frac{-14}{9}\right)\right]$[$​​\because$using commutativity and associativity]
$=\frac{-3}{4} \times\left(\frac{-2}{3}\right)$
$=\frac{1}{2}$
