Răspuns:
1. [tex]\frac{x}{3} + \frac{x}{3} + \frac{x}{3}[/tex]
2. [tex]\frac{x}{2} + \frac{x}{3} + \frac{x}{6}[/tex]
3. [tex]\frac{x}{5} + \frac{2x}{5} + \frac{2x}{5}[/tex]
Explicație pas cu pas:
1. [tex]\frac{x}{3} + \frac{x}{3} + \frac{x}{3}[/tex] = x
2. [tex]\frac{x}{2} + \frac{x}{3} + \frac{x}{6}[/tex] = [tex]\frac{6x}{6} = x[/tex]
3. [tex]\frac{x}{5} + \frac{2x}{5} + \frac{2x}{5}[/tex] [tex]= \frac{5x}{5} = x[/tex]
