НОМЕР 34!!!!!СРОЧНО ПОМОГИТЕ!!!

Решите задачу:

$\frac{4 \frac{1}{3}:( \frac{5}{6}+0.25) }{( \frac{7}{12}- \frac{2}{5}):0.9 } - \frac{3.6( \frac{7}{12}+\frac{1}{9}) }{(\frac{5}{8}-\frac{1}{3})1 \frac{5}{7} } = \frac{ \frac{13}{3}:\frac{13}{12} }{\frac{9}{20}:\frac{9}{10}} - \frac{\frac{36}{10}*\frac{25}{36}}{\frac{7}{24}*\frac{12}{7}} = \frac{4}{\frac{1}{2}} - \frac{2.5}{\frac{1}{2}} =8-5=3$
