Answer
$\frac{3}{4}$
Work Step by Step
Find the least common denominator.
$12=2\times2\times3$
$8=\underline2\times\underline2\times\underline2$
$24=2\times2\times2\times\underline3$
$LCD=2\times2\times2\times3=24$
$\frac{11}{12}-\frac{3}{8}+\frac{5}{24}$ $\longrightarrow$ convert to like fractions
=$\frac{11\times2}{12\times2}-\frac{3\times3}{8\times3}+\frac{5}{24}$ $\longrightarrow$ simplify
=$\frac{22}{24}-\frac{9}{24}+\frac{5}{24}$ $\longrightarrow$ subtract numerators
=$\frac{22-9+5}{24}$ $\longrightarrow$ subtract
=$\frac{18}{24}$ $\longrightarrow$ reduce
=$\frac{18\div6}{24\div6}$ $\longrightarrow$divide
=$\frac{3}{4}$
