x+y
____
1+x
espero que tenham entendido a conta

Answer 1

1/2 +1/4   /  1+1/2
3/4 / 3/2
3/4 .2/3
6/12
1/2

Answer 2

   Sendo
               $x= \frac{1}{2} \\ \\ y= \frac{1}{4} \\ \\ \frac{x+y}{1+x} \\ \\ = \frac{ \frac{1}{2} + \frac{1}{4} }{1+ \frac{1}{2} } \\ \\ = \frac{ \frac{2}{4}+ \frac{1}{4} }{ \frac{2}{2} +\frac{1}{2} } \\ \\ = \frac{ \frac{3}{4} }{ \frac{3}{2} } \\ \\ = \frac{3x2}{4x3}$

               $= \frac{2}{4} \\ \\ = \frac{1}{2}$
