Don't worry about a common denominator. Multiply the top half of the first fraction by the top half of the second. Multiply the bottom half of the fraction by the bottom half of the second. Put them on top of eachother.

\(\displaystyle \frac{3}{4}\ * \frac{-2}{3}\ = \frac{-2*3}{4*3}\ = \frac{-6}{12}\\)
