Вариант 1. 3. Выполните действие: \(\left(11\frac{2}{3}-8\frac{3}{4}\right)+\left(3\frac{1}{3}+2\frac{5}{6}\right)-4\frac{7}{12}\).

Question

Вопрос:

Accepted Answer

\(11\frac{2}{3}-8\frac{3}{4}=\frac{140}{12}-\frac{105}{12}=\frac{35}{12}\).

\(3\frac{1}{3}+2\frac{5}{6}=\frac{20}{6}+\frac{17}{6}=\frac{37}{6}=\frac{74}{12}\).

\(\frac{35}{12}+\frac{74}{12}-\frac{55}{12}=\frac{54}{12}=4\frac{1}{2}\).

Ответ: \(4\frac{1}{2}\).
