1) $7 + \frac{1}{8} = 7\frac{1}{8};$

2) $\frac{5}{13} + 2 = 2\frac{5}{13};$

3) $7\frac{10}{19} + \frac{2}{19} = 7\frac{12}{19};$

4) $2 + 3\frac{2}{5} = (2 + 3) + \frac{2}{5} = 5\frac{2}{5};$

5) $4\frac{1}{19} + 2\frac{2}{19} = (4 + 2) + (\frac{1}{19} + \frac{2}{19}) = 6\frac{3}{19};$

6) $8\frac{3}{10} + 4\frac{7}{10} = (8 + 4) + (\frac{3}{10} + \frac{7}{10}) = 12\frac{10}{10} = 13.$
