Answer
$\frac{8}{15}$
Work Step by Step
$\frac{1}{3} + \frac{1}{5}$
the least common denominator for the denominators 3 and 5 is 15.
To obtain denominators of 15, multiply the numerator and denominator of the first fraction by 5 and the second fraction by 3
$\frac{1}{3} + \frac{1}{5}$ = $\frac{1*5}{3*5} + \frac{1*3}{5*3}$
$\frac{5}{15} + \frac{3}{15}$
Add the numerators and put this sum over the least common denominator.
$\frac{5+3}{15}$ = $\frac{8}{15}$
