    Simple problem, effect of a denominator on a numerator with a square root.

    Why does sq(12) / 12 become sq(3) / 6 ?

     \frac{\sqrt{12}}{12}

     = \frac{\sqrt{4 \times 3}}{2 \times 6}

     = \frac{\sqrt{4}\times\sqrt{3}}{2 \times 6}

     = \frac{2\sqrt{3}}{2\times 6}

     = \frac{\sqrt{3}}{6}
