$(4\frac{2}{3} + 5\frac{1}{2}) * 6 = 4 * 6 + \frac{2}{3} * 6 + 5 * 6 + \frac{1}{2} * 6 = 24 + 4 + 30 + 3 = 61$
$(3\frac{2}{7} + \frac{5}{7}) * 7 = 3 * 7 + \frac{2}{7} * 7 + \frac{5}{7} * 7 = 21 + 2 + 5 = 28$
$(8 - 1\frac{1}{9}) * 9 = 8 * 9 - 1 * 9 - \frac{1}{9} * 9 = 72 - 9 - 1 = 62$
$(4 - 1\frac{1}{3} * 2) * 15 = (2 - 1\frac{1}{3}) * 2 * 15 = \frac{2}{3} * 30 = 2 * 10 = 20$
$8\frac{5}{11} * 4\frac{2}{9} + 8\frac{5}{11} * 6\frac{7}{9} = 8\frac{5}{11} * (4\frac{2}{9} + 6\frac{7}{9}) = 8\frac{5}{11} * 11 = 8 * 11 + \frac{5}{11} * 11 = 88 + 5 = 93$
$6\frac{3}{5} * 7\frac{1}{6} - 2\frac{1}{6} * 6\frac{3}{5} = 6\frac{3}{5} * (7\frac{1}{6} - 2\frac{1}{6}) = 6\frac{3}{5} * 5 = 6 * 5 + \frac{3}{5} * 5 = 30 + 3 = 33$
$9\frac{3}{8} * 2\frac{5}{7} - 2\frac{5}{7} * 7\frac{3}{8} = 2\frac{5}{7} * (9\frac{3}{8} - 7\frac{3}{8}) = 2\frac{5}{7} * 2 = 2 * 2 + \frac{5}{7} * 2 = 4 + \frac{10}{7} = 4\frac{10}{7} = 5\frac{3}{7}$
$3\frac{3}{4} * 3\frac{3}{4} + 3\frac{3}{4} * \frac{1}{4} = 3\frac{3}{4} * (3\frac{3}{4} + \frac{1}{4}) = 3\frac{3}{4} * 4 = 3 * 4 + \frac{3}{4} * 4 = 12 + 3 = 15$
