Best ResponseYou've already chosen the best response.0Look for the lowest common denominator, which is \[(b5)*(5b)\] Remember that you want the fraction to stay the same even after you multiply to get the lowest common denominator, so multiply by 1: \[\frac{5b}{5b} = \frac{b5}{b5} = 1\] \[(\frac{5b}{5b}*\frac{7}{b5})  (\frac{b5}{b5}*\frac{8}{5b})\] \[\frac{(357b)(8b40)}{b^{2}+10b25}\] You can do the rest :)
