Step-by-step explanation:
Let the fraction will be X and Y. According to the question/
(x+2)/(y+2)=9/11
or, 11x+22=9y+18
or, 11x-9y=18-22
or, 11x-9y=-4
or, 11x=9y-4
or, x=(9y-4)/11
and, (x+3)/(y+3)=5/6
then, x=(9×9-4)/11
then, x=(9×9-4)/11or, x=(81-4)/11
then, x=(9×9-4)/11or, x=(81-4)/11or, x=77/11=7
so x=7,y=9 and the fraction is :7/9

Let the numerator of the fraction be x
Let the numerator of the fraction be x & its denominator be y.
Fraction=
Case 1️⃣
When 2 is added to both numerator & denominator,then
Case 2️⃣
When 3 is added to both numerator & denominator, then
On putting value of x in (1), we get
On putting y in equation (2), we get
So, the required fraction
