Answer
$\frac{13}{30}$
Work Step by Step
$\frac{3}{10} + \frac{2}{15}$
the least common denominator for the denominators 10 and 15 is 30.
To obtain denominators of 30, multiply the numerator and denominator of the first fraction by 3 and second fraction by 2
$\frac{3}{10} + \frac{2}{15}$ = $\frac{3*3}{10*3} + \frac{2*2}{15*2}$
$\frac{9}{30} + \frac{4}{30}$
Add the numerators and put this sum over the least common denominator.
$\frac{9+4}{30}$ = $\frac{13}{30}$
