$$\begin{lgathered}\frac{ {(20)}^{2} }{5} \times \frac{6}{9} \times \frac{7}{2} \times \frac{4}{2} \times 3 - 65 + \frac{95}{5} - \frac{65}{95} \times 65 \\ = \frac{20 \times 20}{5} \times \frac{6}{9} \times \frac{7}{2} \times \frac{4}{2} \times 3 - 65 + \frac{95}{5} - \frac{65}{95} \times 65 \\ = 80 \times \frac{2}{3} \times \frac{7}{2} \times 2 \times 3 - 65 + 19 - \frac{13}{19} \times 65 \\ = 1120 - 65 + 19 - \frac{845}{19} \\ = 1120 - 84 - \frac{845}{19} \\ = 1036 - \frac{845}{19} \\ = \frac{19684 - 845}{19} \\ = \frac{18839}{19} \\ = 991\frac{10}{19}\end{lgathered}$$
