Answer
Along direction of $v$: $\frac{1}{3}<2,-1,2>$
Opposite direction of $v$: $-\frac{1}{3}<2,-1,2>$
Work Step by Step
$\mathbf{v}=<2,-1,2>$
$\|\mathbf{v}\|=\sqrt{4+1+4}=3$
Unit Vector in the direction of $\mathbf{v}$: $\frac{1}{3}<2,-1,2>$
Unit Vector in the opposite direction of $\mathbf{v}$: $-\frac{1}{3}<2,-1,2>$
