- $\frac{4}{5} + \frac{1}{3} = \frac{12}{15} + \frac{5}{15} = \frac{17}{15} = 1\frac{2}{15}$
- $\frac{7}{8} + 3\frac{1}{4} = \frac{7}{8} + \frac{13}{4} = \frac{7}{8} + \frac{26}{8} = \frac{33}{8} = 4\frac{1}{8}$
- $\frac{2}{10} + \frac{3}{8} = \frac{1}{5} + \frac{3}{8} = \frac{8}{40} + \frac{15}{40} = \frac{23}{40}$
- $\frac{1}{7} + \frac{3}{12} = \frac{1}{7} + \frac{1}{4} = \frac{4}{28} + \frac{7}{28} = \frac{11}{28}$
- $\frac{2}{8} + \frac{1}{5} = \frac{1}{4} + \frac{1}{5} = \frac{5}{20} + \frac{4}{20} = \frac{9}{20}$
- $2\frac{7}{9} + \frac{1}{2} = \frac{25}{9} + \frac{1}{2} = \frac{50}{18} + \frac{9}{18} = \frac{59}{18} = 3\frac{5}{18}$
- $\frac{8}{11} - \frac{1}{3} = \frac{24}{33} - \frac{11}{33} = \frac{13}{33}$
- $2\frac{2}{5} - \frac{3}{4} = \frac{12}{5} - \frac{3}{4} = \frac{48}{20} - \frac{15}{20} = \frac{33}{20} = 1\frac{13}{20}$
- $\frac{8}{12} - \frac{2}{6} = \frac{2}{3} - \frac{1}{3} = \frac{1}{3}$
- $1\frac{7}{9} - \frac{2}{3} = \frac{16}{9} - \frac{6}{9} = \frac{10}{9} = 1\frac{1}{9}$
- $3\frac{2}{5} - \frac{4}{6} = \frac{17}{5} - \frac{2}{3} = \frac{51}{15} - \frac{10}{15} = \frac{41}{15} = 2\frac{11}{15}$
- $\frac{9}{10} - \frac{2}{3} = \frac{27}{30} - \frac{20}{30} = \frac{7}{30}$
