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
