Question

If numerator is 2 less than
denominator of a rational
number and when 1 is
subtracted from numerator and
denominator both, then we will
get the rational number 1/2.
what is the rational number?
3/5

4/5

3/7​

Answer 1

Answer:

3/5 is correct answer

Explanation:

Suppose the denominator of the rational number is x.Then, according to the question, numerator = Denominator – 2= x – 2Now

On cross multiplying we get,2(x-2-1) = x -1⇒ 2(x-3) = x-1⇒ 2x – 6 = x- 1⇒ x = 5Hence, the denominator = 5And numerator = 5-2 = 3∴ the rational number =3/5
