$- 7$

#### Explanation:

=$\frac{1}{5} - \left(20 \times \frac{\textcolor{red}{\left(81 \div 9\right)}}{25}\right)$

Solve the inner bracket, $\textcolor{b l u e}{81 \div 9 = 9}$, so

=$\frac{1}{5} - \left(\frac{\left(20 \times \textcolor{b l u e}{9}\right)}{25}\right)$

Solve $\textcolor{b r o w n}{20 \times 9 = 180}$

=$\frac{5}{25} - \frac{180}{25}$

=$\frac{5 - 180}{25}$

= $- \frac{175}{25}$

= $- 7$
