Ответ:
Преобразуем смешанные числа: \(2\frac{11}{12}=\frac{35}{12}\), \(2\frac{2}{27}=\frac{56}{27}\).
\(\frac{35}{12}:\frac{7}{16}=\frac{35}{12}\cdot\frac{16}{7}=\frac{20}{3}\).
\(8-\frac{20}{3}=\frac{4}{3}\).
\(\frac{4}{3}:\frac{56}{27}=\frac{4}{3}\cdot\frac{27}{56}=\frac{9}{14}\).
Ответ: \(\frac{9}{14}\).
