Just wrap it in an ol, that way the numbering is dynamic:

<ol> 
   <% @records.each do |record| %>
     <li><%= record %></li>  
   <% end %>
</ol>

Take a look at each_with_index:

<% @records.each_with_index do |record, index| %>

You probably want each_with_index. something like: 

<% @records.each_with_index do |record, i| %>
   <%= (i+1) %>. <%= record.foo %> <br />
<% end %>

you can use each_with_index:

<% @records.each_with_index do |record, i| %>

  #your code

<% end %>
