Answer
$\frac{19}{24}$
Work Step by Step
$\frac{3}{8} + \frac{5}{12}$
the least common denominator for the denominators 8 and 12 is 24.
To obtain denominators of 24, multiply the numerator and denominator of the first fraction by 3 and second fraction by 2
$\frac{3}{8} + \frac{5}{12}$ = $\frac{3*3}{8*3} + \frac{5*2}{12*2}$
$\frac{9}{24} + \frac{10}{24}$
Add the numerators and put this sum over the least common denominator.
$\frac{9+10}{24}$ = $\frac{19}{24}$
