Homework Statement


I'm having a brain fart, how do you factor/simplify a fraction such as [itex]\frac{ab}{ab+cd}[/itex]
I keep thinking multiply by ab-bc but I'm not sure.

Uh, the terms in the denominator have common factor b. Why don't you factor it out?

I'm sorry I miss typed it after using latex format. It's suppose to be DC not BC.

Then I don't think there is any form that is terribly much simpler than what you written. You can change the form, like to 1/(1+(cd)/(ab)), but I don't think the alternate forms are much simpler.

Thank you! This actually does. I should of stated I'm doing transfer functions for circuit design and thats the type of form desired. Thank you!
