Answer :
- The fraction is 9/17.
Given :-
- The numerator of a fraction is 8 less that the denominator. When, 2 is added to both numerator and denominator, fraction becomes 11/9.
To Find :-
- The fraction ?
Solution :-
- Let the Denominator be x.
- And Numerator be (x - 8)
Where, 2 is added,
- 2 is added to denominator = (x + 2)
- 2 is added to numerator = x - 8 + 2 = (x - 6)
• Putting all values,
➻ (x - 6)/(x + 2) = 11/19
➻ 19(x - 6) = 11(x + 2)
➻ 19x - 144 = 11x + 22
➻ 19x - 11x = 22 + 114
➻ 8x = 136
➻ x = 136/8
➻ x = 17
Therefore,
➻ Denominator x = 17
➻ Numerator = x - 8 = 17 - 8 = 9
- Hence, the fraction is 9/17.
