title_body: Is there a way to produce an epub with numbered equations?
upvoted_answer: It would help if provided a sample of the content to give a better answer or suggestion. Are the equations in html, mathml, or as images? What is your current html output for the equations, do you have a sample you could share?
  
  If your number is wrapped in a tag with a unique css class, then you could use css to float the number to the right.
  
  Example html:
  
  
  
  &lt;p&gt;The para with your equation &lt;span class="eq"&gt;1/2&lt;/span&gt;&lt;span class="eq_num"&gt;(1)&lt;/span&gt;&lt;/p&gt;
  
  
  Example css
  
  
  
  span.eq_nu {float: right;}
