title: How to keep fractions in your equation output
body: <p>I've been using Python to calculate math equations. For example:</p>
  
  <pre><code>from sympy import Symbol, Derivative, Integral
  x = Symbol('x')
  d = Symbol('d')
  Integral(8*x**(6/5)-7*x**(3/2),x).doit()
  </code></pre>
  
  <p>Which results in the output:</p>
  
  <pre><code>3.63636363636364*x**2.2 - 2.8*x**2.5
  </code></pre>
  
  <p>Is there a way to show this answer as fractions as opposed to decimals? I would like to see the output as:</p>
  
  <pre><code>(40/11)*x**(11/5)-(14/5)*x**(5/2)+C
  </code></pre>
