$\frac{7}{5} + \frac{3}{5} = \frac{10}{5} \\ \frac{5}{4} + \frac{9}{4} = \frac{14}{4} \\ \frac{6}{8} + \frac{7}{8} = \frac{13}{8} \\ \frac{2}{7} + \frac{3}{7} = \frac{5}{7} \\ \frac{2}{6} + \frac{9}{6} = \frac{11}{6} \\ \frac{9}{12} + \frac{8}{12} = \frac{17}{12}$

$\frac{4}{2} + \frac{1}{2} = \frac{5}{2} \\ \frac{6}{7} + \frac{2}{7} + \frac{3}{7} = \frac{11}{7} \\2 + \frac{3}{4} + \frac{1}{4} = 3 \\ \frac{4}{32} + \frac{19}{32} + \frac{8}{32} = \frac{31}{32}$

$\frac{3}{2} - \frac{2}{2} = \frac{1}{2} \\ \frac{11}{20} - \frac{9}{20} = \frac{2}{20} \\ 1 - \frac{2}{5} = \frac{3}{5} \\ \frac{9}{11} - \frac{4}{11} - \frac{3}{11} = \frac{2}{11} \\ \frac{12}{12} - \frac{3}{12} - \frac{2}{12} = \frac{7}{12}$

$\frac{40}{99} - \frac{27}{99} - \frac{8}{99} = \frac{5}{99} \\ \frac{4}{15} + ( \frac{8}{15} - \frac{3}{15} ) = \frac{3}{5} \\ \frac{2}{39} + ( \frac{35}{39} - \frac{17}{39} + \frac{4}{39} ) = \frac{8}{13}$
