Work Step by Step

To simplify this expression, we first need to find the common denominator (the LCM) of every denominator, which is $12$. Therefore, we obtain: $\frac{3}{4}+\frac{2}{3}-\frac{1}{6}+\frac{5}{12}$ =$\frac{3(3)+2(4)-1(2)+5(1)}{12}$ =$\frac{9+8-2+5}{12}$ =$\frac{17+3}{12}$ =$\frac{20}{12}$ =$\frac{5}{3}$
