Решение:
а) \(\frac{16}{27} : \frac{9}{4} = \frac{16}{27} \cdot \frac{4}{9} = \frac{64}{243}\)
б) \(\frac{42}{5} : \frac{55}{7} = \frac{42}{5} \cdot \frac{7}{55} = \frac{294}{275}\)
в) \(\frac{7}{12} : \frac{3}{12} = \frac{7}{12} \cdot \frac{12}{3} = \frac{7}{3}\)
г) \(\frac{14}{55} : \frac{7}{22} = \frac{14}{55} \cdot \frac{22}{7} = \frac{2 \cdot 2}{5} = \frac{4}{5}\)
Ответ: а) \(\frac{64}{243}\); б) \(\frac{294}{275}\); в) \(\frac{7}{3}\); г) \(\frac{4}{5}\).
