Ex1.3, 6 Look at several examples of rational numbers in the form / (q 0), where p and q are integers with no common factors other than 1 and having terminating decimal representations (expansions). Can you guess what property q must satisfy? Let us take 1/2 , 1/4 , 7/8 , 37/25 , 8/125 ,17/20 , 31/16 etc. which has terminating decimal expansion Hence, in / , q is either 2 or power of 2 or 5 or power of 5 or both
