a) $$\frac{5}{9}:\frac{27}{10}$$ =$$\frac{5}{9} \cdot \frac{10}{27}$$ =$$\frac{50}{243}$$

б) 4$$\frac{4}{5}:2\frac{2}{3}$$ =$$\frac{24}{5}:\frac{8}{3}$$ =$$\frac{24}{5} \cdot \frac{3}{8}$$ =$$\frac{3\cdot 3}{5}$$ =$$\frac{9}{5}$$= 1$$\frac{4}{5}$$

в) 32$$\frac{8}{9}$$ : $$\frac{8}{9}$$ =$$\frac{296}{9}:\frac{8}{9}$$ =$$\frac{296}{9} \cdot \frac{9}{8}$$ =$$\frac{296}{8}$$=37

г) 1$$\frac{12}{13}$$:6 =$$\frac{25}{13}:6$$=$$\frac{25}{13} \cdot \frac{1}{6}$$ =$$\frac{25}{78}$$

д) $$\frac{5}{6}:\frac{7}{9}$$ =$$\frac{5}{6} \cdot \frac{9}{7}$$ =$$\frac{5 \cdot 3}{2 \cdot 7}$$ =$$\frac{15}{14}$$= 1$$\frac{1}{14}$$

ж) $$\frac{11}{28}:\frac{7}{33}$$ =$$\frac{11}{28} \cdot \frac{33}{7}$$ =$$\frac{11 \cdot 33}{28 \cdot 7}$$ =$$\frac{363}{196}$$= 1$$\frac{167}{196}$$

з) 1$$\frac{4}{25}:\frac{4}{11}$$ =$$\frac{29}{25}:\frac{4}{11}$$ =$$\frac{29}{25} \cdot \frac{11}{4}$$ =$$\frac{319}{100}$$= 3$$\frac{19}{100}$$

Ответ: a) $$\frac{50}{243}$$; б) 1$$\frac{4}{5}$$; в) 37; г) $$\frac{25}{78}$$; д) 1$$\frac{1}{14}$$; ж) 1$$\frac{167}{196}$$; з) 3$$\frac{19}{100}$$
