#### Answer

$\frac{107}{10}$

#### Work Step by Step

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.
