$\frac{1}{7} + \frac{6}{7} = \frac{7}{7} = 1$
$\frac{3}{5} + 4\frac{2}{5} = 4\frac{5}{5} = 5$
$9 - \frac{1}{6} = 8\frac{6}{6} - \frac{1}{6} = 8\frac{5}{6}$
$7 + 13\frac{3}{11} = 20\frac{3}{11}$
$9 - 1\frac{1}{2} = 8\frac{2}{2} - 1\frac{1}{2} = 7\frac{1}{2}$
$3\frac{3}{4} - 2 = 1\frac{3}{4}$
$1\frac{1}{100} - \frac{9}{100} = \frac{101}{100} - \frac{9}{100} = \frac{92}{100}$
$\frac{7}{10} + 5\frac{4}{10} = 5\frac{11}{10} = 6\frac{1}{10}$
