(\(\frac{15}{16}\) : \(\frac{25}{22}\)) / (\(\frac{5}{7}\) : \(1\,\frac{1}{14}\)).
Числитель: \(\frac{15}{16}\) · \(\frac{22}{25}\) = \(\frac{33}{40}\). Знаменатель: \(\frac{5}{7}\) · \(\frac{14}{15}\) = \(\frac{2}{3}\). Частное: \(\frac{33}{40}\) · \(\frac{3}{2}\) = \(\frac{99}{80}\) = \(1\,\frac{19}{80}\).
