Let denominator be y then numerator will be y-3 then fraction =y-3/y
Now acc. To ques.
y-3+2/y+5=1/2
We get,
y-1/y+5=1/2
Cross multiplying them
2(y-1)=y+5
2y-2=y+5
=2y-y=5+2
=y=7

Now numerator is y-3=7-3=4

So fraction =4/7

Let the denominator be x
then numerator will be x-3.

The denominator and the numerator is increased by 5 and 2 respectively.
  So deno=x+5
       num=x-3+2 = x-1
x-1/x+5 = 1/2
we have to cross multiply
then we'll get 2x-2=5+x
   x = 7
the denominator = x, so the ans: 7
the numerator   = x-3,so the ans: 4
