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