2) (6 3/4 − 5 1/8 : 1 9/32) · 5/11.

Преобразуем смешанные числа: \(6\frac{3}{4}=\frac{27}{4}\), \(5\frac{1}{8}=\frac{41}{8}\), \(1\frac{9}{32}=\frac{41}{32}\).

Деление дробей: \(\frac{41}{8}:\frac{41}{32}=\frac{41}{8}\cdot\frac{32}{41}=4\).

\(\left(\frac{27}{4}-4\right)\cdot\frac{5}{11}=\frac{11}{4}\cdot\frac{5}{11}=\frac{5}{4}=1\frac{1}{4}\).

Ответ: \(1\frac{1}{4}\).
