Problem: A unit vector parallel to vector V = (2, -3, 6) is ?

Answer is (-.29, .43, -.85)

Thanks. I thought to find a parallel vector you have to multiply through by the same number, so I chose the answer (-2, 3, -6)

Ok, and can the length be -7, as well? As in divide through by -7 to find the right answer? That is what my book says, so I just wanted to verify this.
