$1 - \frac{3}{4} = \frac{4}{4} - \frac{3}{4} = \frac{1}{4}$
$2 - \frac{5}{6} = 1\frac{6}{6} - \frac{5}{6} = 1\frac{1}{6}$
$9 - \frac{11}{12} = 8\frac{12}{12} - \frac{11}{12} = 8\frac{1}{12}$
$7 - 1\frac{7}{8} = 6\frac{8}{8} - 1\frac{7}{8} = 5\frac{1}{8}$
$5 - 2\frac{2}{5} = 4\frac{5}{5} - 2\frac{2}{5} = 2\frac{3}{5}$
$6 - 5\frac{5}{8} = 5\frac{8}{8} - 5\frac{5}{8} = \frac{3}{8}$
$8\frac{3}{11} - 4 = 4\frac{3}{11}$
$5\frac{7}{15} - \frac{3}{20} = 5\frac{28}{60} - \frac{9}{60} = 5\frac{19}{60}$
$1\frac{5}{12} - \frac{9}{10} = 1\frac{20}{60} - \frac{54}{60} = \frac{80}{60} - \frac{54}{60} = \frac{26}{60} = \frac{13}{30}$
$6\frac{3}{10} - \frac{11}{15} = 6\frac{9}{30} - \frac{22}{30} = 5\frac{39}{30} - \frac{22}{30} = 5\frac{17}{30}$
$5\frac{7}{8} - \frac{9}{10} = 5\frac{7}{40} - \frac{36}{40} = 4\frac{47}{40} - \frac{36}{40} = 4\frac{11}{40}$
$7\frac{5}{12} - 3\frac{2}{9} = 7\frac{15}{36} - 3\frac{8}{36} = 4\frac{7}{36}$
$10\frac{1}{2} - 4\frac{9}{14} = 10\frac{7}{14} - 4\frac{9}{14} = 9\frac{21}{14} - 4\frac{9}{14} = 5\frac{12}{14} = 5\frac{6}{7}$
$7\frac{4}{7} - 5\frac{7}{9} = 7\frac{36}{63} - 5\frac{49}{63} = 6\frac{99}{63} - 5\frac{49}{63} = 1\frac{50}{63}$
$2\frac{3}{10} - 1\frac{11}{15} = 2\frac{9}{30} - 1\frac{22}{30} = 1\frac{39}{30} - 1\frac{22}{30} = \frac{17}{30}$
$5\frac{3}{8} - 3\frac{5}{6} = 5\frac{9}{24} - 3\frac{20}{24} = 4\frac{33}{24} - 3\frac{20}{24} = 1\frac{13}{24}$
