2 1/3/(5/8-8/3)-2*1 3/7

Answer 1

$2 \frac{1}{3} \div ( \frac{5}{8} - \frac{8}{3} ) - 2 \times 1 \frac{3}{7} = \\ = \frac{7}{3} \div ( \frac{15}{24} - \frac{64}{24} ) - 2 \times \frac{10}{7} =$

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

$\frac{1 \times 8}{1 \times 7} - \frac{20}{7} = \frac{8}{7} - 2 \frac{6}{7} = - \frac{12}{7} = - 1 \frac{5}{7}$

Ответ: $- 1 \frac{5}{7}$

Answer 2

Ответ:6 11/14

Объяснение:

21/3÷(5/8-8/3)-2×13/7

1) 5/8-8/3=2/3

2)21/3÷2/3=21/3×3/2=21/2

3) 2×13/7=26/7

4)21/2-26/7= 147/14-52/14=95/14=6 11/14
