−23⋅125⋅−157=85=1.6\frac{-2}{3} \cdot 1\frac{2}{5} \cdot -1\frac{5}{7} = \frac{8}{5} = 1.63−2⋅152⋅−175=58=1.6
−23⋅125⋅−157=−23⋅75⋅−157=−1415⋅−157=−1415⋅−(127)=−1415⋅−127=85\begin{aligned}\frac{-2}{3} \cdot 1\frac{2}{5} \cdot -1\frac{5}{7}&=\frac{-2}{3} \cdot \frac{7}{5} \cdot -1\frac{5}{7}\\&=\frac{-14}{15} \cdot -1\frac{5}{7}\\&=\frac{-14}{15} \cdot -\left( \frac{12}{7} \right)\\&=\frac{-14}{15} \cdot \frac{-12}{7}\\&=\frac{8}{5}\end{aligned}3−2⋅152⋅−175=3−2⋅57⋅−175=15−14⋅−175=15−14⋅−(712)=15−14⋅7−12=58
