There is one integer on top, called the numerator, one integer on the bottom, called the denominator, and a line in the middle.</p> <p>$$\frac{a}{b} = \frac{integer}{integer} = \frac{numerator}{denominator}$$</p> <p>Of course the denominator can&nbsp;<strong><span style="color:#e74c3c;"><u>never</u></span></strong> be $0$.</p> <p><span style="color:#8e44ad;"><span style="font-size:20px;">A Couple of Notes</span></span></p> <ol> <li>&nbsp;Integers like $27$ or $5!$ are fractions because they can simply be written as $\frac{27}{1}$ and $\frac{5!}{1}$.</li> <li>A number like $\frac{\sqrt{2}}{3}$ is&nbsp;<strong><u>not</u></strong>&nbsp;a fraction because the numerator is not an integer.&nbsp;</li> <li>Fractions can be <u><strong>SIMPLIFIED</strong></u>. For example...</li> </ol> <p>$$\frac{18}{24} = \frac{9}{12} = \frac{3}{4}$$</p> <p>This &quot;reduction&quot; process stops when the numerator and denominator share no common factors.</p>
