multilpying nad dividing rational expressions

I searched Google under the key words "rational expressions multiply divide" to get these possible sources:
http://www.math.csi.cuny.edu/~lewisc/lcm.pdf
http://www.ltcconline.net/greenl/courses/152b/FactoringRatExpr/ratexp.htm
http://www.helpalgebra.com/articles/rationalexpressions.htm
http://www.mathwarehouse.com/algebra/rationalexpression/howtomultiplydividerationalexpressions.php
http://www.algebraonline.com/dividingrationalexpressions1.htm
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
