Answer

$\frac{11}{14}$

Work Step by Step

We start with: $\frac{4}{7}$+$\frac{3}{14}$ We need a common denominator (bottom of the fraction) to add the numerators (tops of the fractions). Thus, we multiply $\frac{4}{7}$ by $\frac{2}{2}$ to get $\frac{8}{14}$. (This is legal because $\frac{2}{2}$ is equal to one). We now have: $\frac{8}{14}$+$\frac{3}{14}$ Because we have the same denominators, we can add the numerators to obtain: $\frac{11}{14}$
