Relatively basic fraction multplication!
Hi all,
The below expression is part of a longer equation which I have simplified for this example. I would like to remove the r from the very bottom denominator. What do I multiply the remaining variables by?
a/b * (1-cd)/(1-(cd/r)) + e/f
Many thanks in advance!

i assume that by "very bottom denominator" you mean the
part.
multiply everything by 1/r
} + \frac{e}{fr})

oh dear, how silly of me, if you wanted a fraction that was equivalent to he first one, that wont be it....as the above is multiplied by (1/r)
hopefully you made appropriate adjustments to ther est of your equation.

1 - cd/r = (r - cd) / r
So:
a/b * [r(1 - cd) / (r - cd)] + e/f
