Answer 1

Answer:

Step-by-step explanation:

Let numerator=x

Let denominator=y

Fraction will= x/y

A fraction becomes 9/11 ,if 2 is added to both numerator or denominator.

(X+2)/(y+2)=9/11

By cross multiply

11x+22=9y+18

Subtract 22 from both side

11x=9y-4

x = 9y-4/11 _eqution 1

Given that 3 is added to both numerator or denominator then it becomes 5/6

(x+3)/(y+3)=5/6_equrion 2

By cross multiply

6x+18=5y+15

Subtract the value of x

6(9y-4)/11=5y-3

54y-24=55y-33

y = 9

Put this value of y in equation 1

x = 9y-4/11

x= 9×9-4/11

x= 81-4/11

x= 7

So fraction is x/y = 7/9
