a) $\frac{4}{3}$
б) $\frac{19}{26}$
в) 35
г) $\frac{1}{8}$
д) $\frac{7}{44}$

a) $\frac{2}{9} : \frac{9}{14} = \frac{2}{9} * \frac{14}{9} = \frac{28}{91}$
б) $\frac{8}{11} : \frac{4}{33} = \frac{8}{11} * \frac{33}{4} = 2 * 3 = 6$
в) $\frac{7}{17} : \frac{28}{51} = \frac{7}{17} * \frac{51}{28} = \frac{3}{4}$
г) $\frac{6}{13} : \frac{8}{91} = \frac{6}{13} * \frac{91}{8} = \frac{3*7}{4} = \frac{21}{4} = 5\frac{1}{4}$
д) $42 : \frac{6}{7} = \frac{42}{1} * \frac{7}{6} = 7*7 = 49$
е) $3\frac{3}{5} : 2\frac{7}{10} = \frac{18}{5} : \frac{27}{10} = \frac{18}{5} * \frac{10}{27} = \frac{6}{1} * \frac{2}{7} = \frac{12}{7}$
