Keyword to remove square roots out of the denominator

Hi,

How would be the preferred way to remove Square Roots in the denominator from a Mathematica answer?

After enter

v = {1, -1, +1}/Sqrt[(1)^2 + (-1)^2 + (1)^2]

Mathematica returns the answer of

{1/Sqrt[3], -(1/Sqrt[3]), 1/Sqrt[3]}

However, I want to remove the Sqrt’s from the denominator as in

{Sqrt[3]/3, -(Sqrt[3]/3), Sqrt[3]/3}

I have tried to multiply the Mathematica answer using

v*{Sqrt[3]/Sqrt[3], Sqrt[3]/Sqrt[3], Sqrt[3]/Sqrt[3]} 

or even

v*Sqrt[3]/Sqrt[3] 

and still I do not get the answer of {Sqrt[3]/3, -(Sqrt[3]/3), Sqrt[3]/3}.

I have search the internet and website and cannot find a keyword that will allow me to remove Sqrt’s from the denominator of my Mathematica answer. I am using Mathematica Version 9.

Thanks,

v HoldForm[Sqrt[3]]/Sqrt[3]
results in
