Выполни действия 1 ) 2 2 / 11 × 7 / 8 : 7 / 11; 2) 1 1/3×2 2/3:4/9; 5) 8 1/3×1/57:2/8/21

Решите задачу:

$2 \frac{2}{11}* \frac{7}{8}: \frac{7}{11}= \frac{24}{11}* \frac{7}{8}* \frac{11}{7}= \frac{24}{8}=3 \\ 1 \frac{1}{3}*2 \frac{2}{3}: \frac{4}{9}= \frac{4}{3}* \frac{8}{3}* \frac{9}{4}= 8 \\ 8 \frac{1}{3} * 1\frac{5}{7}:2 \frac{8}{21}=\frac{25}{3} * \frac{12}{7}* \frac{21}{50}= \frac{12}{2}=6$
