Л) -\(\frac{2}{11}\)-0,8+0,3\(\cdot\)\(\left\)\(-\frac{2}{11}\right\)

Решение:

\(-\frac{2}{11}-0,8+0,3\cdot\left(-\frac{2}{11}\right) = \left(-\frac{2}{11}\right) - \frac{8}{10} + \left(-\frac{3}{10}\right)\cdot\left(-\frac{2}{11}\right) = \left(-\frac{2}{11}\right) - \frac{4}{5} + \frac{6}{110} = \left(-\frac{2}{11}\right) - \frac{4}{5} + \frac{3}{55} = \frac{-10 - 44 + 3}{55} = \frac{-51}{55}\)

Ответ: -\( \frac{51}{55} \)
