"the ratio of economy to luxury cars is 3 : 1 - - > e : l = 3 : 1 = 12 : 4 . the ratio of economy cars to sport utility vehicles is 4 : 3 - - > e : s = 4 : 3 = 12 : 9 . thus , l : s = 4 : 9 . answer : b ."
divide(divide(multiply(const_4, 3), multiply(3, 3)), divide(multiply(3, const_4), multiply(1, const_4)))
