$\frac{4}{5} + \frac{1}{15} = \frac{12 + 1}{15} = \frac{12}{15}$
$\frac{6}{8} + \frac{1}{24} = \frac{18 + 1}{24} = \frac{19}{24}$
$\frac{18}{32} - \frac{1}{8} = \frac{18 - 8}{32} = \frac{10}{32} = \frac{5}{16}$
$\frac{9}{10} - \frac{1}{2} = \frac{9 - 5}{10} = \frac{4}{10} = \frac{2}{5}$
$\frac{5}{6} + \frac{1}{7} = \frac{35 + 6}{42} = \frac{41}{42}$
$\frac{1}{6} + \frac{1}{4} = \frac{4 + 6}{24} = \frac{10}{24} = \frac{5}{12}$
