title: css calc number division
body: <p>If I use a calculator, <code>2/3</code> is <code>0.6666666667</code> which is about <code>67%</code>. However if I try to do the same thing with css calc I get an error.</p>
  
  <pre><code>width: calc(2 / 3);
  </code></pre>
  
  <p>Is there a working way for this?</p>
  
  <p>I don't think it looks that good writing it like <code>0.666666666667</code>. Any ideas are welcome.</p>
