Let the numerator be x .
Denominator = x+K.
Now, as per the question,
x/2(x+K) = x/(x+K)
i.e. x/2 = x =>x = 2x
which means x = 0.
So, the rational number will 0/(0+K) i.e. 0/K,where K is any constant.
Denominator = x+K.
Now, as per the question,
x/2(x+K) = x/(x+K)
i.e. x/2 = x =>x = 2x
which means x = 0.
So, the rational number will 0/(0+K) i.e. 0/K,where K is any constant.
