1/3(2 2/15*6 1/4-5 1/3*1 1/8)+4 5/9 30 4/5-1 2/5*(1 4/5*(12 7/12-9 19/36)- 17/35*1 11/34)...

Решение на первое:

$2 \frac{2}{15}* 6\frac{1}{4}= \frac{32}{15}* \frac{25}{4}= \frac{800}{60}= \frac{40}{3}$

$5\frac{1}{3} *1 \frac{1}{8}= \frac{16}{3}* \frac{9}{8}= \frac{144}{24}=6$

$\frac{40}{3} - \frac{6}{1}= \frac{40-6*3}{3}= \frac{22}{3}$

$\frac{1}{3}* \frac{22}{3}= \frac{22}{9}$

$\frac{22}{9}+ 4\frac{5}{9}= \frac{22}{9}+ \frac{41}{9}= \frac{63}{9} =7$
