3. Упростите выражение 2$$\frac{2}{3}x – 1\frac{1}{2}x + 1\frac{1}{12}x.

Решение:

2$$\frac{2}{3}x$$ – 1$$\frac{1}{2}x$$ + 1$$\frac{1}{12}x$$ = (2$$\frac{2}{3}$$ – 1$$\frac{1}{2}$$ + 1$$\frac{1}{12}$$)$$\cdot$$x = (2$$\frac{8}{12}$$ – 1$$\frac{6}{12}$$ + 1$$\frac{1}{12}$$)$$\cdot$$x = (1$$\frac{2}{12}$$ + 1$$\frac{1}{12}$$)$$\cdot$$x = 2$$\frac{3}{12}x$$ = 2$$\frac{1}{4}x

Ответ: 2$$\frac{1}{4}x
