Answer

$\frac{2}{3}$

Work Step by Step

$\frac{7}{12} + \frac{1}{12}$ The sum of two fractions with same denominators is the sum of their numerators over the common denominator. $\frac{7+1}{12}$ = $\frac{8}{12}$ Since 4 is the greatest common factor of 8 and 12, divide numerator and denominator by 4 $\frac{2*4}{3*4}$ = $\frac{2}{3}$
