Ответ:
\(1\frac{2}{11}=\frac{13}{11}\), \(3\frac{1}{4}=\frac{13}{4}\).
\[\frac{13}{11}:\frac{13}{4}=\frac{13}{11}\cdot\frac{4}{13}=\frac{4}{11}.\]
Ответ: \(\frac{4}{11}\).
\(1\frac{2}{11}=\frac{13}{11}\), \(3\frac{1}{4}=\frac{13}{4}\).
\[\frac{13}{11}:\frac{13}{4}=\frac{13}{11}\cdot\frac{4}{13}=\frac{4}{11}.\]
Ответ: \(\frac{4}{11}\).
