<p><strong><span style="color:#e74c3c;">Irrational numbers</span></strong> are numbers that <strong><u>cannot</u></strong> be written as a fraction. Remember, something like $\frac{\pi}{3}$ is not a fraction because the numerator in this case is not an integer.</p>
<p><span style="color:#8e44ad;"><span style="font-size:20px;">Where do these terms come from?</span></span></p>
<p>Another way to say fraction is of course "ratio." So rational numbers are ones that can be written as a "ratio." Irrational numbers are ones that cannot be written as a "ratio". Get it? Pretty cool!</p>
