Work Step by Step

We can add the 1 and 2 separately to get 3. We now must add the fractions. In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 4/7 by 2/2 to obtain: $\frac{8}{14}$+($\frac{3}{14}$)=$\frac{11}{14}$. We add 3 to this to get an answer of 3$\frac{11}{14}$.
