[tex]4 \frac{1}{2} - 2 \frac{6}{12} \div ( 2\frac{1}{2} + 1\frac{1}{4} ) \\ \frac{9}{2} - \frac{30}{12} \div ( \frac{5}{2} + \frac{5}{4} ) \\ \frac{9}{2} - \frac{30}{12} \div ( \frac{10 + 5}{4} ) \\ \frac{9}{2} - \frac{30}{12} \div \frac{15}{4} \\ \frac{9}{2} - \frac{30}{12} \times \frac{4}{15} \\ \frac{9}{2} - \frac{2}{3} \\ \frac{54 - 8}{12} = \frac{46}{12} = \frac{23}{6} [/tex]
