- $\frac{2}{5} - \frac{1}{5} = \frac{1}{5}$
- $\frac{4}{9} - \frac{1}{9} = \frac{3}{9}$
- $\frac{5}{7} + \frac{1}{7} = \frac{6}{7}$
- $\frac{2}{4} + \frac{1}{4} = \frac{3}{4}$
- $\frac{7}{10} - \frac{4}{10} = \frac{3}{10}$
- $\frac{4}{6} - \frac{1}{6} = \frac{3}{6}$
- $\frac{2}{4} + \frac{1}{4} = \frac{3}{4}$
- $\frac{2}{11} + \frac{1}{11} = \frac{3}{11}$
- $\frac{1}{3} + \frac{1}{3} = \frac{2}{3}$
- $\frac{2}{3} - \frac{1}{3} = \frac{1}{3}$
- $\frac{3}{8} - \frac{1}{8} = \frac{2}{8}$
- $\frac{4}{12} - \frac{1}{12} = \frac{3}{12}$
- $\frac{3}{6} + \frac{1}{6} = \frac{4}{6}$
- $\frac{3}{5} - \frac{2}{5} = \frac{1}{5}$
