Answer
$\frac{3}{4}$
Work Step by Step
$\frac{3}{8} + \frac{3}{8}$
The sum of two fractions with same denominators is the sum of their numerators over the common denominator.
$\frac{3+3}{8}$ = $\frac{6}{8}$
Since 2 is the greatest common factor of 6 and 8, divide numerator and denominator by 2
$\frac{3*2}{4*2}$ = $\frac{3}{4}$
