Ответ:
- \(\frac{8}{11}:\frac{16}{77}=\frac{8}{11}\cdot\frac{77}{16}=\frac{7}{2}=3\frac{1}{2}\).
- \(\frac{5}{23}:\frac{15}{46}=\frac{5}{23}\cdot\frac{46}{15}=\frac{2}{3}\).
- \(\frac{14}{25}:\frac{21}{50}=\frac{14}{25}\cdot\frac{50}{21}=\frac{4}{3}=1\frac{1}{3}\).
Ответ: \(3\frac{1}{2};\ \frac{2}{3};\ 1\frac{1}{3}\).
