If a/b is the probability that the reciprocal of a randomly selected positive odd integer less than 2010 gives a terminating decimal, with a and b being relatively prime positive integers, what is a+b?
well it has to be # odd powers of 5 up to 2010/# of odd integers between 1-2010 inlcusive. Got 4/1005 4+1005=1009 wrong
