$9\frac{3}{7} * \frac{5}{22} = \frac{66}{7} * \frac{5}{22} = \frac{3}{7} * \frac{5}{1} = \frac{3}{7} * \frac{5}{1} = \frac{15}{7} = 2\frac{1}{7}$
$6\frac{3}{8} * \frac{16}{17} = \frac{51}{8} * \frac{16}{17} = \frac{3}{1} * \frac{2}{1} = 6$
$2\frac{1}{3} * 1\frac{1}{5} = \frac{7}{3} * \frac{6}{5} = \frac{7}{1} * \frac{2}{5} = \frac{14}{5} = 2\frac{4}{5}$
$19\frac{1}{2} * 1\frac{5}{9} = \frac{39}{2} * \frac{14}{9} = \frac{13}{1} * \frac{7}{3} = \frac{91}{3} = 30\frac{1}{3}$
$2\frac{1}{4} * 2\frac{2}{27} = \frac{9}{4} * \frac{56}{27} = \frac{1}{1} * \frac{14}{3} = 4\frac{2}{3}$
$2\frac{8}{11} * 5\frac{2}{15} = \frac{30}{11} * \frac{77}{15} = \frac{2}{1} * \frac{7}{1} = 14$
$\frac{7}{9} * 1\frac{1}{14} * 5\frac{2}{5} = \frac{7}{9} * \frac{15}{14} * \frac{27}{5} = \frac{1}{1} * \frac{3}{2} * \frac{3}{1} = \frac{9}{2} = 4\frac{1}{2}$
$2\frac{2}{3} * 1\frac{1}{24} * 5\frac{2}{5} = \frac{8}{3} * \frac{25}{24} * \frac{27}{5} = \frac{1}{1} * \frac{5}{1} * \frac{3}{1} = 15$
