title: Perform division by a variable using CPLEX
body: <p>As far as I know, CPLEX allows to use the following methods:</p>
  
  <pre><code>addition method : sum()
  multiplication method : prod()
  subtraction method : diff()
  </code></pre>
  
  <p>I Am wondering if it is possible to perform a division by a variable, and if not, what are the possible workarounds.</p>
  
  <p>Thanks in advance.</p>
