Look at several examples of rational numbers in the form p/q (q ≠ 0), where p and q are integers with no common factors other than 1 and having terminating decimal representations. Can you guess what property q must satisfy?

A rational number p/q is a terminating decimal only, when prime factors of q are q and 5 only. Therefore, p/q is a terminating decimal only, when prime factorization of q must have only powers of 2 or 5 or both.
