1. Answer:

   Let the fraction be

   y

   x

   Given that

   y+2

   x+2

   =

   11

   9

   ⇒11x+22=9y+18

   ⇒11x−9y+4=0→i

   ⇒

   y+3

   x+3

   =

   6

   5

   ⇒6x+18=5y+15

   ⇒6x−5y+3=0→ii

   ⇒i×5−ii×9

   ⇒55x−45y+20=0

   ⇒54x−45y+27=0

   eq(i)−eq(ii)

   ⇒x−7=0

   ⇒x=7

   ⇒y=

   9

   11x+4

   =

   9

   11(7)+4

   =

   9

   81

   =9

   ∴Fraction is

   y

   x

   =

   9
