\[\frac{18}{25} : \frac{3}{5} = \frac{18}{25} \cdot \frac{5}{3} = \frac{6}{5} \cdot \frac{1}{1} = \frac{6}{5} = 1\frac{1}{5}\]
Ответ: \[1\frac{1}{5}\]
\[560 : \frac{7}{12} = 560 \cdot \frac{12}{7} = 80 \cdot 12 = 960\]
Ответ: 960
\[\frac{81}{155} : \frac{54}{95} = \frac{81}{155} \cdot \frac{95}{54} = \frac{9}{31} \cdot \frac{19}{6} = \frac{3}{31} \cdot \frac{19}{2} = \frac{57}{62}\]
Ответ: \[\frac{57}{62}\]
\[990 : \frac{9}{11} = 990 \cdot \frac{11}{9} = 110 \cdot 11 = 1210\]
Ответ: 1210
\[\frac{36}{77} : \frac{42}{55} = \frac{36}{77} \cdot \frac{55}{42} = \frac{6}{7} \cdot \frac{5}{7} = \frac{30}{49}\]
Ответ: \[\frac{30}{49}\]
\[36 : \frac{27}{64} = 36 \cdot \frac{64}{27} = 4 \cdot \frac{64}{3} = \frac{256}{3} = 85\frac{1}{3}\]
Ответ: \[85\frac{1}{3}\]
