Answer 1

Ответ:

$2 \frac{1}{3} \div ( \frac{5}{8} - \frac{8}{3} ) - 2 \times 1 \frac{3}{7}$

$\frac{7}{3} \div ( \frac{15}{24} - \frac{64}{24} ) - 2 \times \frac{10}{7}$

$\frac{7}{3} \div ( - \frac{49}{24} ) - \ \frac{20}{7} = - \frac{7 \times 24} {3 \times 49} - \frac{20}{7}$

$- \frac{8}{7} - \frac{20}{7} = - \frac{28}{7} = - 4$
