(C) To find the number of decimal places for a rational number $\frac{p}{q}$ where $q = 2^n \cdot 5^m$,the number of decimal places is equal to $\max(n, m)$.Given the expression $\frac{18}{5^{3}}$,we can rewrite the denominator as $2^0 \cdot 5^3$.Here,$n = 0$ and $m = 3$.The number of decimal places is $\max(0, 3) = 3$.Thus,the decimal expansion terminates after $3$ decimal places.

The decimal expansion of $\frac{18}{5^{3}}$ will terminate after how many decimal places?
