#### Answer

7$\frac{11}{12}$

#### Work Step by Step

We start by subtracting the whole numbers: $12-4=8$. In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 3/4 by 3/3 and 5/6 by 2/2 to obtain: $\frac{9}{12}-$($\frac{10}{12}$)=-$\frac{1}{12}$. We add the 8 to get an answer of 7$\frac{11}{12}$
