Answer 1

$a) \: 1 \frac{5}{9} - \frac{8}{9} = \frac{14}{9} - \frac{8}{9} = \frac{14 - 8}{9} = \frac{6}{9} = \frac{2}{3} \\ b) \: 1 \frac{1}{12} - \frac{5}{12} = \frac{13}{12} - \frac{5}{12} = \frac{13 - 5}{12} = \frac{8}{12} = \frac{2}{3} \\ c) \: 8 \frac{3}{7} - 5 \frac{5}{7} = \frac{59}{7} - \frac{40}{7} = \frac{59 - 40}{7} = \frac{19}{7} = 2 \frac{5}{7} \\ d) \:4 \frac{1}{8} - 1 \frac{5}{8} = \frac{33}{8} - \frac{13}{8} = \frac{33 - 13}{8} = \frac{20}{8} = \frac{5}{2} = 2 \frac{1}{2}$
