[tex] - 4 \frac{1}{4} - ( - 8 \frac{2}{9} - 4.5 \div ( - \frac{ \\9}{14} )) \times 2.25 \\ - \frac{17}{4} - ( - \frac{74}{9} - \frac{9}{14} )) \times \frac{9}{4} [/tex]

[tex] - \frac{17}{4} - ( - \frac{74}{9} + \frac{9}{2} \times \frac{14}{9} ) \times \frac{9}{4} \\ - \frac{17}{4} - ( - \frac{74}{9} + 7) \times \frac{9}{4} [/tex]

[tex] - \frac{17}{4} - ( - \frac{11}{9} ) \times \frac{9}{4} \\ - \frac{17}{4} + \frac{11}{9} \times \frac{9}{4}[/tex]

[tex] - \frac{17}{4} + 11 \times \frac{1}{4} \\ - \frac{17}{4} + \frac{11}{4} = - \frac{3}{2} [/tex]
