Two dogs, Rufus and Daisy, are eating dinner. The amount of food (measured in grams) and Rufus's bowl after t minutes is R(t) = 450-150t, and the amount of food (measured in grams) in Daisy's bowl after t minutes is D(t)= 400 - 120t. Express the ratio of the amount remaining in Daisy's bowl to the amount remaining in Rufus's bowl as a rational function, and simplify.
