Помогите решить пример срочно!!!

Решите задачу:

$\displaystyle\frac{(\frac{1}{6}+0,1+\frac{1}{15}):(\frac{1}{6}+0,1-\frac{1}{15})}{(0,5-\frac{1}{3}+0,25-0,2):(0,25-\frac{1}{6})}=$

$\displaystyle\frac{(\frac{5}{30}+\frac{3}{30}+\frac{2}{30} ):(\frac{5}{30}+\frac{3}{30}-\frac{2}{30})}{(0,55-\frac{1}{3}):(0,25-\frac{1}{6})}=$

$\displaystyle\frac{\frac{10}{30}:\frac{6}{30}}{(\frac{55\cdot3}{300}-\frac{100}{300}):(\frac{6}{24}-\frac{4}{24})}=\frac{\frac{10\cdot30}{30\cdot6}}{\frac{65}{300}:\frac{2}{24}}=\frac{\frac{5}{3}}{\frac{65\cdot24}{300\cdot2}}=\frac{\frac{5}{3}}{\frac{65}{25}}=\frac{5\cdot25}{(65)\cdot3}=\frac{25}{39}$
