Simplify:

(4) $\frac{9}{7}\times \left(\frac{-14}{15}\times \frac{2}{3}\right)$

Answer 1

$$\begin{gathered} \frac{9}{7}\times \left(\frac{-14}{15}\times \frac{2}{3}\right) \\ =\frac{9}{7}\times \left(\frac{-28}{45}\right) \\ =\frac{9}{7}\times \frac{-4\times 7}{9\times 5} \\ =\frac{1}{1}\times \frac{-4}{5} \\ =\frac{-4}{5} \end{gathered}$$
