Ответ:
\(-8\frac{3}{5}+\frac{6}{5}+4\frac{1}{6}=-\frac{43}{5}+\frac{6}{5}+\frac{25}{6}=-\frac{37}{5}+\frac{25}{6}=\frac{-222+125}{30}=-\frac{97}{30}\).
\(-\frac{97}{30}:\frac{8}{25}=-\frac{97}{30}\cdot\frac{25}{8}=-\frac{485}{48}\).
\(\frac{3}{4}-\frac{485}{48}=\frac{36-485}{48}=-\frac{449}{48}=-9\frac{17}{48}\).
Ответ: \(-9\frac{17}{48}\).
