​

Answer 1

$\frac{x}{y} = {( \frac{ - 2}{3}) }^{3} \div { (\frac{3}{5}) }^{ - 2} \\ \\ = > \frac{x}{y} = \frac{( - 2) \times ( - 2) \times ( - 2)}{3 \times 3 \times 3} \div {( \frac{5}{3}) }^{2} \\ \\ = > \frac{x}{y} = \frac{ - 8}{27} \times \frac{3 \times 3}{5 \times 5} \\ \\ = > \frac{x}{y} = \frac{ - 8}{27} \times \frac{9}{25} \\ \\ = > \frac{x}{y} = \frac{ - 8}{75}$
