$\frac{2}{9} + \frac{5}{6} = \frac{4}{18} + \frac{15}{18} = \frac{19}{18} = 1 \times \frac{1}{18}$
$\frac{2}{26} + \frac{3}{39} = \frac{6}{78} + \frac{6}{78} = \frac{12}{78} = \frac{2}{13}$

$\frac{2}{10} + \frac{6}{15} = \frac{6}{30} + \frac{12}{30} = \frac{18}{30} = \frac{3}{5}$
$\frac{5}{12} + \frac{4}{15} = \frac{25}{60} + \frac{16}{60} = \frac{41}{60}$
