Question

The numerator of a rational number is 6 less than ots denominator . If 3 is added to the numerator , the fraction is equal to 2/3 . Find the original fraction . Why the original fraction cannot be 1/3 ?​

Answer 1

Answer:

Let the numerator of the rational number be x. 

Then, the denominator of the rational number =x+3

According to the given condition,

New numerator =3x and new denominator =(x+3)+20=x+23

Given, x+233x=81 

By cross multiplying, we get

8(3x)=x+23

⇒24x=x+23

⇒23x=23 ....[On Transposing]

or x=1

Therefore, numerator of the rational number =1 and denominator =1+3=4.

Hence, the original rational number is 41.
