\[9\frac{1}{4} \cdot 8 - 1\frac{2}{3} \cdot 5\frac{1}{2} - 2\frac{4}{5} \cdot 2\frac{11}{12} =\]
\[= \frac{37 \cdot 8}{4} - \frac{5 \cdot 11}{3 \cdot 2} - \frac{14 \cdot 35}{5 \cdot 12} =\]
\[= 74 - \frac{55}{6} - \frac{49}{6} =\]
\[= 74 - \frac{104}{6} = 74 - 17\frac{2}{6} =\]
\[= 73\frac{3}{3} - 17\frac{1}{3} = 56\frac{2}{3}\]
