Răspuns:
[tex]\frac{2}{3}[/tex]
Explicație pas cu pas:
Bună!
[tex]2\frac{1}{3} +3\frac{1}{2} -5\frac{1}{6} =[/tex]
[tex]=\frac{2*3+1}{3} +\frac{3*2+1}{2} -\frac{5*6+1}{6} =[/tex]
[tex]=^{2)} \frac{7}{3} +^{3)} \frac{7}{2} -\frac{31}{6} =[/tex]
[tex]=\frac{14+21-31}{6} =\frac{35-31}{6} =\frac{4}{6}^{(2} =\frac{2}{3}[/tex]
