$Фото задания: 8. $(5\frac{7}{10}\cdot3\frac{1}{7})-(7\frac{1}{3}-4\frac{5}{9}):2\frac{1}{6}$$ Фото задания

Accepted Answer

$5\frac{7}{10}\cdot3\frac{1}{7}=\frac{57}{10}\cdot\frac{22}{7}=\frac{627}{35}$.

$7\frac{1}{3}-4\frac{5}{9}=\frac{22}{3}-\frac{41}{9}=\frac{25}{9}$.

$\frac{25}{9}:\frac{13}{6}=\frac{50}{39}$.

$\frac{627}{35}-\frac{50}{39}=\frac{22703}{1365}$.

Ответ: $\frac{22703}{1365}$.
