Question

Rational number p/q, q ≠ 0 will be terminating decimal if the prime factorisation of q is of the form. (m and n are non negative integers):

• A. 2^m x 5ⁿ
• B. 3^m x 7ⁿ
• C. 3^m x 5ⁿ
• D. 2^m x 3ⁿ

Answer 1

The correct option is A

2^m x 5ⁿ

Rational number p/q, q ≠ 0 will be terminating decimal if the prime factorisation of q is of the form 2^m x 5ⁿ.
