See a solution process below:

One process for solving this is:

$6 \frac{7}{10} + 3 \frac{9}{10} \Rightarrow$ $6 7/10 + 3 9/10 =>$

$6 + \frac{7}{10} + 3 + \frac{9}{10} \Rightarrow$ $6 + 7/10 + 3 + 9/10 =>$

$6 + 3 + \frac{7}{10} + \frac{9}{10} \Rightarrow$ $6 + 3 + 7/10 + 9/10 =>$

$9 + \frac{7 + 9}{10} \Rightarrow$ $9 + (7 + 9)/10 =>$

$9 + \frac{16}{10} \Rightarrow$ $9 + 16/10 =>$

$9 + \frac{10 + 6}{10} \Rightarrow$ $9 + (10 + 6)/10 =>$

$9 + \frac{10}{10} + \frac{6}{10} \Rightarrow$ $9 + 10/10 + 6/10 =>$

$9 + 1 + \frac{3}{5} \Rightarrow$ $9 + 1 + 3/5 =>$

$10 + \frac{3}{5} \Rightarrow$ $10 + 3/5 =>$

$10 \frac{3}{5}$ $10 3/5$
