title: How to scale a value down?
body: <p>I have a variable <code>x</code> that accepts a range of values from 0 - 500. </p>
  
  <p>I want to represdnt this variable's value in a new variable <code>xScaled</code> that accepts a range of 0 - 1. </p>
  
  <p><strong>Example:</strong> 
  <em>Given <code>x = 292</code> what is the relative value of <code>xScaled</code> and how can this be calculated?</em> </p>
  
  <p>Thanks </p>
