[tex]2 \frac{2}{5} + \frac{1}{2} - \frac{7}{10} \\ = \frac{12}{5} + \frac{1}{2} - \frac{7}{10} \\ = \frac{24}{10} + \frac{5}{10} - \frac{7}{10} \\ = \frac{29}{10} - \frac{7}{10} \\ = \frac{22}{10} \\ = 2 \frac{2}{10} [/tex]

disamakan semua penyebutnya : 2 2/5 + 1/2- 7/10
[tex]= 2 \frac{2}{5} + \frac{1}{2} - \frac{7}{10} [/tex]
[tex]= 2 \frac{4}{10} + \frac{5}{10} - \frac{7}{10} [/tex]
[tex]= \frac{24}{10} + \frac{5}{10} - \frac{7}{10} = \frac{24+5-7}{10} [/tex]
[tex]= \frac{22}{10} = 2 \frac{2}{10}[/tex]
