#### Answer

Rationalizing a denominator means eliminating the radical in the denominator.
$\frac{1}{\sqrt 3}$=$\frac{1}{\sqrt 3}$$\times$$\frac{\sqrt 3}{\sqrt 3}$= $\frac{\sqrt 3}{3}$

#### Work Step by Step

To rationalize a denominator, we need to multiply both the numerator and the denominator by the radical. It is equivalent to multiplying by one. Therefore, we do not change the mathematical value of the number.
