Simplify: $\frac{3\frac{1}{3} \div \frac{5}{6} \text{ of } 1\frac{1}{5} + \frac{3}{4} \times 1\frac{1}{3}}{\frac{2}{3} \text{ of } 1\frac{1}{2} - 1\frac{1}{4} \div \frac{5}{6}}$

Using BODMAS, 'of' means multiplication. Numerator: $3\frac{1}{3}=\frac{10}{3}$, $\frac{5}{6}$ of $1\frac{1}{5}=\frac{5}{6}\times\frac{6}{5}=1$, so $\frac{10}{3}\div1 = \frac{10}{3}$. Then $\frac{3}{4}\times\frac{4}{3}=1$. Numerator = $\frac{10}{3}+1=\frac{13}{3}$. Denominator: $\frac{2}{3}$ of $1\frac{1}{2}=\frac{2}{3}\times\frac{3}{2}=1$, $1\frac{1}{4}\div\frac{5}{6}=\frac{5}{4}\times\frac{6}{5}=\frac{3}{2}$. Denominator = $1 - \frac{3}{2} = -\frac{1}{2}$. Result = $\frac{13}{3} \div (-\frac{1}{2}) = -\frac{26}{3}$.
