4. Найдите значение выражения: (-6 1/8) :(-7/9) +(-2 11/14)*1 8/13 + |-3,63| : |-0,22| =

\[\left(-6\frac{1}{8}\right) : \left(-\frac{7}{9}\right) + \left(-2\frac{11}{14}\right) \cdot 1\frac{8}{13} + |-3,63| : |-0,22| = \\ = \left(-\frac{49}{8}\right) : \left(-\frac{7}{9}\right) + \left(-\frac{39}{14}\right) \cdot \frac{21}{13} + 3,63 : 0,22 = \\ = \frac{49}{8} \cdot \frac{9}{7} - \frac{39}{14} \cdot \frac{21}{13} + \frac{3,63}{0,22} = \\ = \frac{7 \cdot 9}{8} - \frac{3 \cdot 3}{2} + 16,5 = \\ = \frac{63}{8} - \frac{9}{2} + 16,5 = \\ = \frac{63}{8} - \frac{36}{8} + \frac{132}{8} = \\ = \frac{63 - 36 + 132}{8} = \frac{159}{8} = 19,875\] Ответ: 19,875
