Вопрос:

7. \((10\frac{1}{6}-6\frac{11}{14})\cdot(2\frac{2}{9}+1\frac{5}{7}):3\frac{2}{3}\)

Ответ:

\(10\frac{1}{6}-6\frac{11}{14}=\frac{61}{6}-\frac{95}{14}=\frac{71}{21}\).

\(2\frac{2}{9}+1\frac{5}{7}=\frac{20}{9}+\frac{12}{7}=\frac{248}{63}\).

\(\frac{71}{21}\cdot\frac{248}{63}:\frac{11}{3}=\frac{71}{21}\cdot\frac{248}{63}\cdot\frac{3}{11}=\frac{17608}{4851}\).

Ответ: \(\frac{17608}{4851}\).
