"the ratio of economy to luxury cars is 5 : 4 - - > e : l = 5 : 4 = 15 : 12 . the ratio of economy cars to sport utility vehicles is 3 : 2 - - > e : s = 3 : 2 = 15 : 10 . thus , l : s = 12 : 10 = 6 : 5 . answer : c ."
divide(divide(multiply(const_4, 2), multiply(2, 2)), divide(multiply(2, const_4), multiply(4, const_4)))
