Question

a rational numbers such that its denominator is greater than its numerator by constant K where K is not equal to zero is the Denominator is doubled the number obtained is again equal to original number find the rational number

Answer 1

Answer:

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.
