Question

Вычислите : 2 1/3:(5/8-8/3)-2•1 3/7​

Answer 1

Ответ:

$2 \frac{1}{3} \div ( \frac{5}{8} - \frac{8}{3} ) - 2 \times 1 \frac{3}{7} = \frac{7}{3} \div ( \frac{15 - 64}{24} ) - 2 \times \frac{10}{7} = \frac{7}{3} \div ( - \frac{ 49}{24}) - \frac{2 \times 10}{7} = - \frac{7 \times 24}{3 \times 49} - \frac{20}{7} = - \frac{8}{7} - \frac{20}{7} = - \frac{28}{7} = - 4$

Answer 2

Пошаговое объяснение:

2 1/3:(5/8-8/3)-2×1 3/7=

=7/3:((15-64)/24)-2×10/7

7/3:(-49/24)-20/7=

= - 7/3×24/49-20/7= - 8/7-20/7=

= - 28/7= - 4
