$1\frac{2}{3} = \frac{1 * 3 + 2}{3} = \frac{3 + 2}{3} = \frac{5}{3}$
$4\frac{3}{7} = \frac{4 * 7 + 3}{7} = \frac{28 + 3}{7} = \frac{31}{7}$
$8\frac{1}{9} = \frac{8 * 9 + 1}{9} = \frac{72 + 1}{9} = \frac{73}{9}$
$10\frac{2}{11} = \frac{10 * 11 + 2}{11} = \frac{110 + 2}{11} = \frac{112}{11}$
$3\frac{1}{100} = \frac{3 * 100 + 1}{100} = \frac{300 + 1}{100} = \frac{301}{100}$
$7\frac{3}{5} = \frac{7 * 5 + 3}{5} = \frac{35 + 3}{5} = \frac{38}{5}$
$6\frac{1}{9} = \frac{6 * 9 + 1}{9} = \frac{54 + 1}{9} = \frac{55}{9}$
$20\frac{3}{17} = \frac{20 * 17 + 3}{17} = \frac{340 + 3}{17} = \frac{343}{17}$
$4\frac{2}{9} = \frac{4 * 9 + 2}{9} = \frac{36 + 2}{9} = \frac{38}{9}$
$5\frac{1}{13} = \frac{5 * 13 + 1}{13} = \frac{65 + 1}{13} = \frac{66}{13}$
$10\frac{3}{11} = \frac{10 * 11 + 3}{11} = \frac{110 + 3}{11} = \frac{113}{11}$
$9\frac{8}{9} = \frac{9 * 9 + 8}{9} = \frac{81 + 8}{9} = \frac{89}{9}$
