Let the fraction (rational number) be x-2/x
Then,x-2+1/x+1=2/3
x-1/x+1=2/3
3(x-1)=2(x+1)
3x-3=2x+2
3x-2x=2+3
x=5
therefore the fraction is 3/5
Then,x-2+1/x+1=2/3
x-1/x+1=2/3
3(x-1)=2(x+1)
3x-3=2x+2
3x-2x=2+3
x=5
therefore the fraction is 3/5

Let the denominator be x then the numerator will be x-2
Now, ATQ
Now x = 5
Then numerator = 5-2 =3
Denominator = 5
Now, ATQ
Now x = 5
Then numerator = 5-2 =3
Denominator = 5
