402. Вычислить: \(\dfrac{-\left(-5\dfrac{4}{45}+4\dfrac{1}{15}\right)\cdot30}{1\dfrac{1}{3}}+\dfrac{-(4,25:0,85+1:0,5)}{(5,56-4,06):3}\).

Question

Вопрос:

Accepted Answer

\[ -5\dfrac{4}{45}+4\dfrac{1}{15}=-\dfrac{229}{45}+\dfrac{61}{15}=-\dfrac{46}{45}. \]

\[\dfrac{-\left(-\dfrac{46}{45}\right)\cdot30}{\frac43}=\dfrac{\frac{92}{3}}{\frac43}=23.\]

\[4,25:0,85+1:0,5=5+2=7,\qquad (5,56-4,06):3=1,5:3=0,5.\]

\[\dfrac{-7}{0,5}=-14.\]

\[23-14=9.\]

Ответ: 9.
