Answer 2

$(\frac{a+b}{2} )+(\frac{b+\frac{a}{2} }{3} )=$

$\frac{a+b}{2} +\frac{\frac{2b}{2}+\frac{a}{2} }{3} =$

$\frac{a+b}{2} +\frac{\frac{2b+a}{2} }{3} =$

$\frac{a+b}{2} +\frac{2b+a}{2} *\frac{1}{3} =$

$\frac{a+b}{2} +\frac{2b+a}{6} =$

$\frac{3(a+b)+2b+a}{6} =$

$\frac{3a+3b+2b+a}{6} =$

$\frac{4a+5b}{6}$
