body: <p>Suppose we have some arbitrary positive number <code>x</code>.</p>
  
  <p>Is there a method to represent its inverse in binary or <code>x</code>'s inverse is <code>1/x</code> - how does one express that in binary?</p>
  
  <p>e.g. <code>x=5 //101</code><br>
  <code>x</code>'s inverse is <code>1/x</code>, it's binary form is ...?</p>
