The answer is 47 / 47.5. I calculated it by adding 45 and 50, then divided it by 2.
(48/47) x (47/46) x (46/45) x . . . . . x (3/2) x (2/1) =(48 x 47 x 46 x . . . . . x 3 x 2) / (47 x 46 x 45 x . . . . . x 2 x 1) =48.Every factor less than 48 in the numerator is canceled by the same numberappearing once in the denominator.Another way to write this thing is (48!)/(47!) which is 48.
