$-\frac{1}{3}-\left(-\frac{7}{8}\right)+\frac{11}{12}$

Remove the parenthesis:
$-\frac{1}{3}+\frac{7}{8}+\frac{11}{12}$

Find the lowest common denominator for the first two: $-\frac{8}{24}+\frac{21}{24}+\frac{11}{12}$

Add: $\frac{-8+21}{24}+\frac{11}{12}$

Add: $\frac{13}{24}+\frac{11}{12}$

Find the lcm: $\frac{13}{24}+\frac{22}{24}$

Add: $\frac{13+22}{24}$

Add: $\frac{35}{24}$
