Question 3 Explanation:

\[\begin{align}
& ?=11\frac{1}{2}+9\frac{5}{6}-5\frac{2}{3}-2\frac{7}{9} \\
& =\left( 11+9-5-2 \right)+\left( \frac{1}{2}+\frac{5}{6}-\frac{2}{3}-\frac{7}{9} \right) \\
& =13+\left( \frac{9+15-12-14}{18} \right) \\
& =13-\frac{2}{18}=13-\frac{1}{9}=12\frac{8}{9} \\
\end{align}\]
