6.Look at several examples of rational numbers in the form p/q ($$q \ne 0$$). 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?
$$1/2 = (1 × 5)/(2 × 5) = 5/10 = 0.5.$$
$$7/125 = (7 × 8)/(125 × 8) = 56/1000 = 0.056$$
$$1/4 = (1 × 25)/(25 × 4) = 25/100 = 0.25$$
$$19/25 = (19 × 4)/(25 × 4) = 76/100 = 0.76$$
