The easiest square roots to simplify are the perfect squares, so if you see a perfect square number in the top or bottom of your fraction, go ahead and turn it into an integer. If the fraction doesn't have an obvious perfect square, try reducing it by dividing by a common factor. If it can't be reduced, then you'll need to simplify each radical separately first and then reduce the fraction coefficients.
