Ж) -\(\frac{2}{3}\)\(\cdot\)\(\left\)\(-\frac{5}{14}\right\)\(\cdot\)\(\frac{3}{8}\)\(\cdot\)\(\frac{7}{5}\)
Ответ:
Решение:
\(-\frac{2}{3}\cdot\left(-\frac{5}{14}\right)\cdot\frac{3}{8}\cdot\frac{7}{5} = \frac{2}{3}\cdot\frac{5}{14}\cdot\frac{3}{8}\cdot\frac{7}{5} = \frac{2\cdot 5\cdot 3\cdot 7}{3\cdot 14\cdot 8\cdot 5} = \frac{210}{3360} = \frac{1}{16}\)
Ответ: \( \frac{1}{16} \)
