Answer:
let the numerator be 'x' and the Denominator be 'y' .
----the fraction is x/y.
As per the 1st condition
y=x+8
x-y=-8 ------(1)
As Per the 2nd condition
numerator=(x+17)
Denominator=(y-1)
(X+17)/(y-1)=3/2
2(x+17)=3(y-1)
2x+34=3y-3
2x-3y= -3-34
2x-3y=-37 --------(2)
Multiplying equation (1)by 3
3x-3y=-24 -------(3)
Adding equation (2)&(3)
2x-3y=-37
3x-3y=-24
_________
5x= -61
X=-61/5
X=-12.5
By putting x=-12.5 in equation 1
x-y=-8
-12.5-y= -8
-y=-8+12.5
-y=4.5
The fraction is -12.5/4.5
