($\sqrt 6$) / 2
1. We must multiply numerator and denominator by $\sqrt 6$ to get rid of radical in the denominator, thus rationalizing 2. Multiplying Numerator by $\sqrt 6$ to get 3$\sqrt 6$ 3. Multiplying Denominator by $\sqrt 6$ you get $\sqrt 36$ which simplifies to 6 4. Our answer is now 3$\sqrt 6$ / 6 which simplifies to ($\sqrt 6$) / 2
