Either there is a typo, and the wording of the problem is not exactly as posted,
or this could be called a trick question.
n= the numerator
d=n%2BK= the denominator
2%2Ad=2%28n%2BK%29= the denominator, doubled

The original number is n%2Fd .
The number with the denominator doubled (just the denominator) is n%2F2d .
For both of those numbers to be equal, the only solution is n=0 .
That would make the original number 0%2FK=0 ,
and the number with the denominator doubled would be 0%2F2K=0.
