Answer 1

.......................

Answer 2

$2 \frac{1}{3}: (\frac{5}{8} - \frac{8}{3} )-2*1 \frac{3}{7}$

1) $\frac{5}{8} - \frac{8}{3} = \frac{15}{24} - \frac{64}{24} = \frac{-49}{24} =-2 \frac{1}{24}$
2) $2 \frac{1}{3} :(-2 \frac{1}{24}) = \frac{7}{3} : (-\frac{49}{24})= \frac{7}{3} * (- \frac{24}{49})= \frac{8}{7} = 1 \frac{1}{7}$
3) $2 * 1 \frac{3}{7} = 2* \frac{10}{7} =2 \frac{6}{7}$
4) $1 \frac{1}{7} - 2 \frac{6}{7}= \frac{8}{7} - \frac{20}{7} = -1 \frac{5}{7}$

Ответ: $-1 \frac{5}{7}$
