We will start by simplifying the expression inside the parenthesis first. 3$\frac{1}{2}$ + 4$\frac{1}{3}$ = (7/2) + (13/3) To add these two fractions, we need a common denominator. Multiplying the denominators together gives us 6, so: (7/2) + (13/3) = (21/6) + (26/6) = 47/6 Now, let's simplify the expression in the denominator: $\frac{5}{6} - \frac{2}{3}$ = $\frac{5}{6} - \frac{4}{6}$ = $\frac{1}{6}$ Finally, we can substitute these values into the original expression: (3$\frac{1}{2}$ + 4$\frac{1}{3}$) ÷ ($\frac{5}{6}$ - $\frac{2}{3}$) = (47/6) ÷ (1/6) When dividing fractions, we can multiply the first fraction by the reciprocal of the second: (47/6) ÷ (1/6) = (47/6) x (6/1) = 47 Therefore, the answer is 47.
