Question

Look at serval examples of rational number in the form p/q (q is not equal to 0), where p and q are integers with no common factors other than 1 and having terminating decimal representation (expansions).Can you guess what property q must satisfy?​

Answer 1

Step-by-step explanation:

Any number that can be represented in p/q where q is greater than 0 is called a rational number. The real numbers cannot be expressed in p/q, where p and q are integers, and q ≠ 0 are known as irrational numbers.

q must satisfy the condition that if prime factors of q have only powers of 2 or power of 5 or both, then the rational numbers always have a terminating decimal expansion.

i.e. 2m×5n , where m=1,2,3,⋯ or n=1,2,3
