Answer:
Let the fraction be x/y
x-1/y-1=1/3
3x-3=y-1
3x-y=-1+3
3x-y=2..............eq 1
x+1/y+1=1/2
2x+2=y+1
2x-y=1-2
2x-y=-1............eq2
By subtracting eq2 from eq1
3x-y=2
2x-y=-1
-. +. +
x=1.........
Put value of x in eq1
3(1)-y=2
3-y=3
6=y..........
Therefore, the fraction is 1/6
Here's ur answer!!!!!!
