(−1 1/8) · (1 1/5 + 4/16) · (−8/9)

Преобразуем смешанные числа и дробь:

\(-1\frac{1}{8}=-\frac{9}{8}\), \(1\frac{1}{5}=\frac{6}{5}\), \(\frac{4}{16}=\frac{1}{4}\).

\[\left(-\frac{9}{8}\right)\cdot\left(\frac{6}{5}+\frac{1}{4}\right)\cdot\left(-\frac{8}{9}\right)=\left(-\frac{9}{8}\right)\cdot\frac{29}{20}\cdot\left(-\frac{8}{9}\right)=\frac{29}{20}=1.45.\]

Ответ: 1,45.
