Best ResponseYou've already chosen the best response.0Your common denominator is r(r8) so you need to create two fractions with r(r8) on the bottom. ????/r(r8) + ????/r(r8). You then ask yourself what do I need to multiply the r on the bottom of the first fraction to get r(r8)....... you need an "r8" so you multiply the top by "r8" and you get 2(r8) = 2r  16 so you now have (2r  16)/(r(r8) + Then you ask yourself what do I need to multiply the "r8" on the bottom of the second fraction to get r(r8).... you need an "r" so you multiply the top by "r" and you get 9r/(r(r8)) so you now have (2r  16)((r(r8)) + 9r/((r(r8)) so you have (11r  16)/(r(r8)) ** You don't need the ( )'s when you write this down, I just used them so you know what is on top of what.. You wil need the r(r8) parentheses.
