Answer 1

$- Procedimiento:$

$\frac{ \frac{1}{1} + \frac{1}{2} }{ \frac{2}{1} + \frac{1}{2} } + \frac{ \frac{2}{1} - \frac{1}{2} }{ \frac{3}{1} - \frac{1}{2} } =$

$\frac{2:1.1+2:2.1}{2:1.2+2:2.1} + \frac{2:1.2-2:2.1}{2:1.3-2:2.1} =$

$\frac{2+1}{4+1} + \frac{4-1}{6-1} =$

$\frac{3}{5} + \frac{3}{5} =$

$\frac{3+3}{5} =$

$\frac{6}{5}$
