Question

Simplify each of the following and express each as a rational number:
${\left(\frac{2}{3}\right)}^2\times {\left(\frac{-3}{5}\right)}^3\times {\left(\frac{7}{2}\right)}^2$

Answer 1

$(\frac{2}{3}{)}^2\times (\frac{-3}{5}{)}^3\times (\frac{7}{2}{)}^2=\frac{4}{9}\times \frac{-27}{125}\times \frac{49}{4}=\frac{147}{125}$
