[tex]( \frac{1}{2} \div \frac{2}{9} + \frac{1}{8} - \frac{3}{4} ) \times \frac{8}{9} = ( \frac{1}{2} \times \frac{9}{2} + \frac{1}{8} - \frac{3}{4} ) \times \frac{8}{9} = ( \frac{9}{2 } + \frac{1}{8} - \frac{3}{4} ) \times \frac{8}{9} = \frac{9}{2} \times \frac{8}{9} + \frac{1}{8} \times \frac{8}{9} - \frac{3}{4} \times \frac{8}{9} = 4 + \frac{1}{9} - \frac{2}{3} = \frac{36 + 1 - 6}{9} = \frac{31}{9} [/tex]
