$4\frac{1}{12} * 8\frac{6}{7} * 6 = \frac{7 * 7 * 2 * 31 * 6}{2 * 6 * 7} = \frac{7 * 31}{1} = 217$
$6\frac{1}{4} * 1\frac{2}{5} * 8 = \frac{25}{4} * \frac{7}{5} * 8 = \frac{5 * 5 * 7 * 4 * 2}{4 * 5} = \frac{5 * 7 * 2}{1} = 70$
$5\frac{3}{7} * \frac{5}{9} * \frac{14}{19} = \frac{38}{7} * \frac{5}{9} * \frac{14}{19} = \frac{19 * 2 * 5 * 7 * 2}{7 * 9 * 19} = \frac{2 * 5 * 2}{9} = \frac{20}{9} = 2\frac{2}{9}$
$3\frac{3}{8} * \frac{1}{2} : \frac{9}{16} = \frac{27}{8} * \frac{1}{2} * \frac{16}{9} = \frac{9 * 3 * 8 * 2}{8 * 2 * 9} = \frac{3}{1} = 3$
$5\frac{5}{7} * \frac{5}{12} * 5\frac{1}{4} * \frac{6}{7} : 1\frac{1}{2} = \frac{40}{7} * \frac{5}{12} * \frac{21}{4} * \frac{6}{7} * \frac{2}{3} = \frac{5 * 4 * 2 * 5 * 21 * 6 * 2}{7 * 4 * 3 * 4 * 21} = \frac{5 * 2 * 5}{7} = \frac{50}{7} = 7\frac{1}{7}$
$\frac{3}{4} * 1\frac{1}{4} * 7\frac{1}{2} * 2\frac{1}{4} : 7\frac{1}{2} = \frac{3}{4} * \frac{5}{4} * \frac{15}{2} * \frac{9}{4} * \frac{15}{2} = \frac{3 * 5 * 15 * 9 * 2}{4 * 4 * 2 * 4 * 15} = \frac{135}{64} = 2\frac{7}{64}$
$\frac{3}{7} : 1\frac{1}{7} : 1\frac{7}{8} : \frac{11}{25} : 1\frac{1}{22} : 3\frac{2}{11} = \frac{3}{7} * \frac{7}{8} * \frac{8}{15} * \frac{25}{11} * \frac{22}{23} * \frac{11}{35} = \frac{3 * 7 * 8 * 5 * 5 * 22 * 11}{7 * 8 * 3 * 5 * 11 * 23 * 7 * 5} = \frac{22}{7 * 23} = \frac{22}{161}$
$\frac{15}{16} : 1\frac{1}{48} : 2\frac{1}{7} : 2\frac{2}{49} : \frac{24}{125} = \frac{15}{16} * \frac{48}{49} * \frac{7}{15} * \frac{49}{100} * \frac{125}{24} = \frac{15 * 2 * 24 * 7 * 49 * 5 * 25}{16 * 49 * 15 * 25 * 4 * 24} = \frac{7 * 5}{8 * 4} = \frac{35}{32} = 1\frac{3}{32}$
