\[\frac{- 4\frac{1}{8} \cdot ( - 2,5) \cdot 1,6}{0,5 \cdot 2\frac{1}{4} \cdot ( - 8,8)} =\]
\[= \frac{- \frac{33}{8} \cdot \left( - \frac{5}{2} \right) \cdot \frac{8}{5}}{\frac{1}{2} \cdot \frac{9}{4} \cdot \left( - \frac{44}{5} \right)} = - \frac{\frac{33}{2}}{\frac{99}{10}} =\]
\[= - \frac{33}{2} \cdot \frac{10}{99} = - \frac{5}{3} = - 1\frac{2}{3}.\]
