П) -2,7\(\cdot\) 7\(\frac{1}{3}\)\(\cdot\)\(\left\)\(-\frac{4}{11}\right\)\(\cdot\)\(\left\)\(-1\frac{9}{4}\right\) \(\cdot\) 0,625

Решение:

\(-2,7\cdot 7\frac{1}{3}\cdot\left(-\frac{4}{11}\right)\cdot\left(-1\frac{9}{4}\right) \cdot 0,625 = \left(-\frac{27}{10}\right)\cdot\frac{22}{3}\cdot\left(-\frac{4}{11}\right)\cdot\left(-\frac{13}{4}\right)\cdot\frac{5}{8} = \frac{27}{10}\cdot\frac{22}{3}\cdot\frac{4}{11}\cdot\frac{13}{4}\cdot\frac{5}{8} = \frac{27 \cdot 22 \cdot 4 \cdot 13 \cdot 5}{10 \cdot 3 \cdot 11 \cdot 4 \cdot 8} = \frac{27 \cdot (2 \cdot 11) \cdot 4 \cdot 13 \cdot 5}{(2 \cdot 5) \cdot 3 \cdot 11 \cdot 4 \cdot 8} = \frac{27 \cdot 13}{3 \cdot 8} = \frac{9 \cdot 13}{8} = \frac{117}{8} = 14\frac{5}{8}\)

Ответ: 14\( \frac{5}{8} \)
