\large{\underline{\underline{\tt{\red{Answer-}}}}}

\large{\boxed{\rm{\blue{Fraction\:=\:\dfrac{7}{9}}}}}

\large{\underline{\underline{\tt{\red{Explanation-}}}}}

Let the numerator and denominator be x and y respectively.

\rightarrow Fraction = \tt{\dfrac{x}{y}}

\bold{\pink{\rm{According\:to\:the\:question-}}}

  • If 2 is added to both the numerator & denominator, the fraction becomes \tt{\dfrac{9}{11}}

\therefore \tt{\dfrac{x+2}{y+2}\:=\:\dfrac{9}{11}}

\rightarrow \tt{11(x+2)\:=\:9(y+2)}

\rightarrow 11x + 22 = 9y + 18

\rightarrow 11x + 22 - 9y - 18 = 0

\rightarrow 11x - 9y = -4

\rightarrow x = \tt{\dfrac{9y-4}{11}} __________(1)

\rule{200}2

  • If 3 is added to both the numerator & denominator it becomes 5/6.

\therefore \tt{\dfrac{x+3}{y+3}\:=\:\dfrac{5}{6}}

\rightarrow 6x + 18 = 5y + 15

Putting the value of x,

\rightarrow 54 - 24 = 55y - 33

\rightarrow \tt{\cancel{-}\:y\:=\:\cancel{-}\:9}

\large{\boxed{\tt{\pink{y\:=\:9}}}}

Now, put the value of y in (1),

\rightarrow x = \tt{\dfrac{81-4}{11}}

\rightarrow x = \tt{\cancel{\dfrac{77}{11}}}

\large{\boxed{\tt{\purple{x\:=\:7}}}}

\rule{200}2

★ Fraction = \tt{\dfrac{x}{y}}

\huge{\rightarrow} \large{\boxed{\rm{\blue{Fraction\:=\:\dfrac{7}{9}}}}}
