Answer
-$\frac{20}{3}$
Work Step by Step
($\frac{1}{2}$+$\frac{1}{3}$)$\div$($\frac{1}{4}$-$\frac{3}{8}$)
First make the sets of fractions have common denominators.
($\frac{1(3)}{2(3)}$+$\frac{1(2)}{3(2)}$)$\div$($\frac{1(2)}{4(2)}$-$\frac{3}{8}$)
($\frac{3}{6}$+$\frac{2}{6}$)$\div$($\frac{2}{8}$-$\frac{3}{8}$)
Then add and subtract inside the sets of parentheses.
($\frac{5}{6}$)$\div$(-$\frac{1}{8}$)
Then change the division to multiplication of the reciprocal of the divisor.
($\frac{5}{6}$)$\times$(-$\frac{8}{1}$)
Then multiply..
-$\frac{40}{6}$
Then reduce by 2.
-$\frac{20}{3}$
