a+b/2+ 2b+a/2/3

a+b/2 + 2b+a/6

3(a+b)+2b+a/6

3a+3b+2b+a/6

4a+5b/6

Baftă!

[tex](\frac{a+b}{2} )+(\frac{b+\frac{a}{2} }{3} )=[/tex]

[tex]\frac{a+b}{2} +\frac{\frac{2b}{2}+\frac{a}{2} }{3} =[/tex]

[tex]\frac{a+b}{2} +\frac{\frac{2b+a}{2} }{3} =[/tex]

[tex]\frac{a+b}{2} +\frac{2b+a}{2} *\frac{1}{3} =[/tex]

[tex]\frac{a+b}{2} +\frac{2b+a}{6} =[/tex]

[tex]\frac{3(a+b)+2b+a}{6} =[/tex]

[tex]\frac{3a+3b+2b+a}{6} =[/tex]

[tex]\frac{4a+5b}{6}[/tex]
