Question

if numerator is 2 less than denominator of a rational number if 1 is subtracted from numerator and denominator both the new rational number obtained is 1 upon 2 what is rational number.

Answer 1

Let the initial number be x/x+2
then new number will be x-1/x+2-1
=x-1/x+1 = 1/2
= 2(x-1) = x+1
= 2x -2 = x+1
= 2x-x = 3
= x= 3
so the initial number was 3/5
