  <p><strong>Where My Question Differs:</strong></p>
  
  <ol>
  <li>Is use of the &lt;sup&gt; and &lt;sub&gt; tags considered the "standard way" of doing fractions in HTML 5?</li>
  <li>If not, what is the way that custom fractions are supposed to be done?</li>
  </ol>
  
  <p><strong>Further Clarifications:</strong></p>
  
  <p>I am <em>not</em> asking <em>how</em> to do custum fractions in HTML 5. I'm looking for what the <em>standard or best practice</em> is. I've seen a lot of different techniques and I'm looking for a solid reference from a reputable source that states what the best approach is in terms of semantics and web standards.</p>
