Oke, so each of the reindeer have 4 feetsies and each of them have 2 ears. (4:2) You would then have to reduce this ratio to be 2:1. Mentioning that santa has 9 reindeer is irrelevant to the question because if you multiply the number of legs and number of ears by the number of reindeer, you'll end up having to reduce it to the same ratio anyways. (9 • 4:2 = 36:18 = 2:1)
Anyhoo, without all the fluff the answer is 2:1 ... I think.
