2 2/7*1 1/6+1/3*2 2/7-1,5*1 2/7 нужно расписать РЕШИТЕ ПЖ!!!

Решите задачу:

$2 \frac{2}{7} * \frac{11}{6} + \frac{1}{3} *2 \frac{2}{7} -1,5*1 \frac{2}{7} =$
$1)2 \frac{2}{7} * \frac{11}{6} = 4 \frac{4}{21}$
$2) \frac{1}{3} * 2 \frac{2}{7} = \frac{16}{21}$
$3) 1,5*1 \frac{2}{7} = 1 \frac{13}{14}$
$4) 4 \frac{4}{21} + \frac{16}{21} = 4 \frac{20}{21}$
$5) 4 \frac{20}{21} -1 \frac{13}{14} = 3 \frac{1}{42}$
