Question

Without doing any actual division, find which of the following rational numbers have terminating decimal representation : `9/14`

Answer 1

Given number is `9/14`

Since 14 = 2 x 7 = 2¹ x 7¹
I.e. 14 cannot be expressed as 2^m x 5ⁿ

∴ `9/14` is not convertible into the terminating decimal.
