# Simple Algebra question (fractions)

Does $\dfrac{-2}{2\sqrt{u}}$ equal $-\sqrt{u}$ or $-\dfrac{1}{\sqrt{u}}$

Perhaps the interesting thing here is to ask why would anyone think the square root in the denominator would/should/could "jump" to the numerator? –  DonAntonio Oct 13 '12 at 10:53

$$\frac{-2}{2\sqrt{u}} = \frac{-1}{\sqrt{u}} = - \frac{1}{\sqrt{u}}$$
