Question

Вычислите: 2 1/3 : (8/3-5/8)+2×1 3/7=

Answer 1

$2 \frac{1}{3} \div ( \frac{8}{3} - \frac{5}{8} ) + 2 \times 1 \frac{3}{7} = \frac{7}{3} \times \frac{49}{24} + \frac{6}{7} = \frac{7 \times 49}{3 \times 24} + \frac{6}{7} = \frac{343}{72} + \frac{6}{7} = \frac{343 \times 7}{72 \times 7} + \frac{6 \times 72}{7 \times 72} = \frac{2401}{504} + \frac{432}{504} = \frac{2401 + 432}{504} = \frac{2833}{504}$
