Question

22 |5/12-4/15|•|1/18+1/2| дробная черта |2/3-5/8|•(-8)

Answer 1

$\frac{ | \frac{5}{12} - \frac{4}{15} | \times | \frac{1}{18} + \frac{1}{2} | }{ | \frac{2}{3} - \frac{5}{8} | \times ( - 8)}$

Выполним по действиям:

$| \frac{5}{12} - \frac{4}{15} | = | \frac{25 - 16}{60} | = | \frac{9}{60} | = \frac{3}{20}$

$| \frac{1}{18} + \frac{1}{2} | = | \frac{1 + 9}{18} | = | \frac{10}{18} | = \frac{5}{9}$
$\frac{3}{20} \times \frac{5}{9} = \frac{3 \times 5}{20 \times 9} = \frac{1}{12}$

$| \frac{2}{3} - \frac{5}{8} | = | \frac{16 - 15}{24} | = | \frac{1}{24} | = \frac{1}{24}$
$\frac{1}{24} \times ( - 8) = - \frac{8}{24} = - \frac{1}{3}$

$\frac{1}{12} \div ( - \frac{1}{3} ) = - \frac{3}{12} = - \frac{1}{4} = -0.25$

ответ: -0.25
