Номер 5 помогите пж срочно надо

Решите задачу:

$2-1 \frac{4}{5} *(1 \frac{1}{4} + \frac{1}{12} ):6=2-1 \frac{4}{5} *(1 \frac{1*3}{4*3} + \frac{1}{12} ):6= \\ \\ \\ =2-1 \frac{4}{5} *(1 \frac{3}{12} + \frac{1}{12} ):6= 2-1 \frac{4}{5} *1 \frac{4}{12} :6= \\ \\ \\ 2-1 \frac{4}{5} *1 \frac{4}{12} * \frac{1}{6}=2-\frac{9}{5} *\frac{16}{12} * \frac{1}{6}= \\ \\ \\ =2-\frac{9}{5} *\frac{16}{72} = 2-\frac{9:9}{5} *\frac{16}{72:9} = \\ \\ \\ =2- \frac{1}{5} * \frac{16}{8}= 2- \frac{1}{5} * \frac{16:8}{8:8}= 2-\frac{1}{5} * \frac{2}{1}= \\ \\ \\$

$= 1 \frac{5}{5} - \frac{2}{5} =1 \frac{3}{5}$
