$\frac{107}{10}$
Convert both fractions to improper fractions. $6\frac{2}{5}$ = $\frac{32}{5}$, $4\frac{3}{10}$ = $\frac{43}{10}$ Make both fractions have the same denominator. $\frac{32}{5}$ = $\frac{32\times2}{5\times2}$ = $\frac{64}{10}$ Add the fractions. $\frac{43}{10} + \frac{64}{10}$ = $\frac{107}{10}$. The numerator and denominator are relatively prime, so this cannot be simplified any further.
