Решение:
\(2\frac{2}{3} \cdot 3\frac{1}{4} - 2\frac{1}{4} \cdot 2\frac{2}{3} = \frac{8}{3} \cdot \frac{13}{4} - \frac{9}{4} \cdot \frac{8}{3} = \frac{8 \cdot 13}{3 \cdot 4} - \frac{9 \cdot 8}{4 \cdot 3} = \frac{104}{12} - \frac{72}{12} = \frac{104 - 72}{12} = \frac{32}{12} = \frac{8}{3} = 2\frac{2}{3}\)
Ответ: \(2\frac{2}{3}\)
