\[9\frac{1}{4} \cdot 8 - 3\frac{2}{3} \cdot 4\frac{1}{2} - 10\frac{4}{5} \cdot 4\frac{7}{12} =\]
\[= \frac{37 \cdot 8}{4} - \frac{11 \cdot 9}{3 \cdot 2} - \frac{54 \cdot 55}{5 \cdot 12} =\]
\[= \frac{37 \cdot 2}{1} - \frac{11 \cdot 3}{1 \cdot 2} - \frac{9 \cdot 11}{1 \cdot 2} =\]
\[= 74 - \frac{33}{2} - \frac{99}{2} = 74 - \frac{132}{2} =\]
\[= 74 - 66 = 8.\]
