z/z=1 (1/18) times 1 is still 1/18 does not change the value now (1/18) times z/z = z/18z which still has the value of 1/18

we multiplied 1/18 by 1 because z/z is 1 ok we multiplied 11/18 by 1 or z/z so it will now look like 11z/18z I thought we were working with 1/18. Still we haven't changed it its value, just its appearance.
