Answer
$\frac{8}{15}$
Work Step by Step
$\frac{2}{5} + \frac{2}{15}$
the least common denominator for the denominators 5 and 15 is 15.
To obtain denominators of 15, multiply the numerator and denominator of the first fraction by 3
$\frac{2}{5} + \frac{2}{15}$ = $\frac{2*3}{5*3} + \frac{2}{15}$
$\frac{6}{15} + \frac{2}{15}$
Add the numerators and put this sum over the least common denominator.
$\frac{6+2}{15}$ = $\frac{8}{15}$
