Heya !!
Let numerator of fraction be X.
Denominator = ( X + 8 )
Fraction = Numerator/Denominator = X/X+8
According to the question,
X + 17 / X + 8 - 1 = 3/2
X + 17 / X + 7 = 3/2
2 ( X + 17 ) = 3 ( X + 7 )
2X + 34 = 3X + 21
3X - 2X = 34 - 21
X = 13
Numerator = X = 13
And,
Denominator = X + 8 = 13+8 = 21
Fraction = 13/21.

hey!!!
ATQ, the denominator of a fraction is greater than the numerator by 8.
let the numerator of the fraction be x. therefore the denominator of the fraction is x + 8
if the numerator is increased by 17 and denominator is decreased by 1, then the number obtained is 3/2
therefore x+17/(x+8)-1 = 3/2
>> x+17/x-7 = 3/2
>> 2(x+17) = 3(x-7)
>> 2x + 34 = 3x - 21
>> 34 + 21 = 3x - 2x
>> 13 = x
hence, the numerator of the fraction is = x = 13
and denominator = x + 8 = 13 + 8 = 21
verification :-
= 13 + 17/ 21 - 1
= 30/20
= 3/2
hence verified!
final answer - 13/21
cheers!!!
