$(3 \frac{7}{5} - \frac{4}{5}) * \frac{25}{18} - ( 1 \frac{8}{20} + 4 \frac{17}{20}) : 1 \frac{1}{4} =$$(4 \frac{2}{5} - \frac{4}{5}) * \frac{25}{18} - ( 1 \frac{2}{5} + 4 \frac{17}{20}) : 1 \frac{1}{4} =$$3 \frac{3}{5}* \frac{25}{18} - 5 \frac{25}{20} : 1 \frac{1}{4} =$$\frac{18}{5}* \frac{25}{18} - \frac{125}{20} * \frac{4}{5} =$$5 - 5 = 0$
