Find the least common denominator (LCM of 15,5,11,2,and 9) and convert all fractions.
Then compare.
D=3%5E2%2A5%2A11%2A2=990
%288%2F15%29%2A%2866%2F66%29=582%2F990
%283%2F5%29%28198%2F198%29=594%2F990
%286%2F11%29%2890%2F90%29=540%2F990
%281%2F2%29%28495%2F495%29=495%2F990
%284%2F9%29%28110%2F110%29=440%2F990
