Question
Without doing any actual division, find which of the following rational numbers have terminating decimal representation : `32/45`
Solution
Given number is `32/45`
Since, 45 = 3 x 3 x 5 = 32 x 51
I.e. 45 cannot be expressed as 2m x 5n
∴ `32/45` is not convertible into the terminating decimal.
