Let the numerator be x.
then denominator is x+8
let the numerator be increased by 1=x+1
let the denominator be decreased by 1=x+8-1  =x+7
hence,x+1/x+7=3/2
by the method of transposition
2(x+1)=3(x+7)
2x+2=3x+21
2x-3x=21-2
-x=19
and the rational number will be -19/-11

Let the numerator be x
hence the denominator will be x+8
numerator increasing 1= x+1
denominator decreasing 1=x+8-1=x+7
by the given condition
x+1/x+7=3/2
taking cross product
2x+2=3x+21
3x-2x=2-21
x= -19
hence the original number is -19/-11
ie 19/11
