Question

$Фото задания: 5. $(9\frac{1}{8}:2\frac{3}{5})+(4\frac{5}{6}-2\frac{7}{12})\cdot1\frac{3}{10}$$ Фото задания

Accepted Answer

$9\frac{1}{8}:2\frac{3}{5}=\frac{73}{8}:\frac{13}{5}=\frac{365}{104}$.

$4\frac{5}{6}-2\frac{7}{12}=\frac{29}{6}-\frac{31}{12}=\frac{9}{4}$.

$\frac{9}{4}\cdot\frac{13}{10}=\frac{117}{40}$.

$\frac{365}{104}+\frac{117}{40}=\frac{1673}{260}$.

Ответ: $\frac{1673}{260}$.
