Solution:-
Let the numerator be x and denominator be y
So,the fraction will be x/y
Given
Numerator is 2 less than denominator
=> x = y - 2 -----> (1)
According to question
(x + 1) / (y + 1) =2/3
Putting value of x from equation (1)
=> (y - 2 + 1) / (y + 1) = 2/3
=> (y - 1) / (y + 1) = 2/3
=> 3y - 3 = 2y + 2
=> y = 2 + 3
=> y = 5
Using equation (1):
=> x = y - 2
=> x = 5 - 2 [putting y = 5]
=> x = 3
Therefore, the fraction is 3/5
