State whether the following rational number has a terminating decimal expansion or not. If it has a terminating decimal expansion,find it: $\frac{29}{343}$

(N/A) To determine if a rational number $\frac{p}{q}$ has a terminating decimal expansion,we check the prime factorization of the denominator $q$. If $q = 2^n \times 5^m$ (where $n, m \ge 0$),the decimal expansion is terminating.
Here,the denominator is $343$.
The prime factorization of $343$ is $7^3$.
Since the denominator is not of the form $2^n \times 5^m$,the rational number $\frac{29}{343}$ does not have a terminating decimal expansion; it has a non-terminating repeating decimal expansion.
