9$\frac{14}{99}$

We start by adding the whole numbers: 5+3=8. In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 7/9 by 11/11 and 4/11 by 9/9 to obtain: $\frac{77}{99}$+($\frac{36}{99}$)=$\frac{113}{99}$. We add the 8 to get an answer of 9$\frac{14}{99}$.
