Yes, here is an example where the normalize vector does not contain any fraction.

Consider a 3 dimensional vector A = (3,4,5). To normalize it, calculate the unit vector u = (x/z, y/z, z/z), where z = (x^2 + y^2 + z^2)^(1/2) = (3^2 + 4^2 + 5^2)^(1/2) = (9 + 16 + 25)^(1/2) = (50)^(1/2) = 7. So, the normalized vector is u = (3/7, 4/7, 5/7).

We can see that by multiplying each component of the normalized vector u by 7, we get back the original vector A.
