<p>You might ask yourself the following question: <strong><span style="color:#27ae60;">Does the fraction terminate</span></strong>? To answer that question, follow these steps:</p>
<ul>
<li>Simplify the fraction to its simplest form so that there are no shared factors among the numerator and denominator.</li>
<li>If there are only powers of $2$ in the denominator, it definitely terminates.</li>
<li>If there are only powers of $5$ in the denominator, it definitely terminates.</li>
<li>If there is a combination of only powers of $2$ and $5$ in the denominator, it definitely terminates.</li>
</ul>
<p><span style="font-size:20px;"><span style="color:#e74c3c;">Example</span></span></p>
<p>$$\frac{n}{2^45^7}$$</p>
<p>If $n$ is an integer -- any integer -- then the fraction above will <strong><u>always</u></strong> terminate. Test it out with some various integers.</p>
