The numerator of a rational is 3 less than the denominator. If the denominator is increased by 5 and numerator by 2 we get the rational no.1/2 . Find the



Let denominator be y then numerator will be y-3 then fraction =y-3/y
Now acc. To ques.
We get,
Cross multiplying them

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

So fraction =4/7
0 0 0
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
