Let us assume the numerator be x
The denominator be (2x – 2)
According formula
Fraction = numerator/denominator
= x / (2x – 2)
So, the numerator and denominator are increased by 3, then fraction is 2/3
(x + 3)/(2x – 2 + 3) = 2/3
(x + 3)/(2x + 1) = 2/3
By doing cross-multiplying
3(x + 3) = 2(2x + 1)
3x + 9 = 4x + 2
3x – 4x = 2 – 9
-x = -7
x = 7
The numerator is x = 7, denominator is (2x – 2) = (2(7) – 2) = 14-2 = 12
And the fraction is numerator/denominator = 7/12
