Question
Has the rational number $\frac{441}{2^2\times5^7\times7^2}$ terminating or a non terminating decimal representation?

Answer

Given rational number is $\frac{441}{2^2\times5^7\times7^2}$
The denominator $(2^2 \times 5^7 \times 7^2)$ of given rational number is not in the from of $(2^m \times 5^n).$
So, this is a non-terminating decimal representation.
