Решите задачу:

$\frac{3^{-1}-(\frac{2}{3})^{-2}}{2-(\frac{3}{4})^2}*(5^0-\frac{1}{6})^{-1}+2*10^{-1} = \\ = \frac{\frac{1}{3}-(\frac{3}{2})^2}{2-(\frac{3}{4})^2}*\frac{1}{1-\frac{1}{6}}+\frac{2}{10}= \\ =\frac{\frac{1}{3}-\frac{9}{4}}{2-\frac{9}{16}}*\frac{1}{\frac{5}{6}}+\frac{2}{10} = \\ = \frac{\frac{4-27}{12}}{\frac{32-9}{16}}*\frac{6}{5}+\frac{2}{10} = \\ = -\frac{23}{12}*\frac{16}{23}*\frac{6}{5}+\frac{2}{10} = \\ = -\frac{4}{3}*\frac{6}{5}+\frac{2}{10} = \\ = \frac{2}{10}-\frac{8}{5} = -\frac{14}{10} = -1,4$
