$\frac{4}{9} : \frac{3}{8} = \frac{4}{9} * \frac{8}{3} = \frac{32}{27} = 1\frac{5}{27}$
$\frac{3}{7} : \frac{9}{14} = \frac{3}{7} * \frac{14}{9} = \frac{1}{1} * \frac{2}{3} = \frac{2}{3}$
$\frac{86}{113} : \frac{43}{51} = \frac{86}{113} * \frac{51}{43} = \frac{2}{113} * \frac{51}{1} = \frac{102}{113}$
$\frac{27}{64} : 9 = \frac{27}{64} * \frac{1}{9} = \frac{3}{64} * \frac{1}{1} = \frac{3}{64}$
$8 : \frac{2}{3} = 8 * \frac{3}{2} = 4 * 3 = 12$
$7 : 3 = 7 * \frac{1}{3} = \frac{7}{3} = 2\frac{1}{3}$
$2\frac{1}{7} : 1\frac{11}{14} = \frac{15}{7} : \frac{25}{14} = \frac{15}{7} * \frac{14}{25} = \frac{3}{1} * \frac{2}{5} = \frac{6}{5} = 1\frac{1}{5}$
$3\frac{3}{5} : 1\frac{11}{25} = \frac{18}{5} : \frac{36}{25} = \frac{18}{5} * \frac{25}{36} = \frac{1}{1} * \frac{5}{2} = 2\frac{1}{2}$
$2\frac{3}{23} : 7\frac{21}{46} = \frac{49}{23} : \frac{343}{46} = \frac{49}{23} * \frac{46}{343} = \frac{1}{1} * \frac{2}{7} = \frac{2}{7}$
$2\frac{47}{49} : 12\frac{3}{7} = \frac{145}{49} : \frac{87}{7} = \frac{145}{49} * \frac{7}{87} = \frac{5}{7} * \frac{1}{3} = \frac{5}{21}$
