Also, you need to indicate that the contents should not be escaped, but delivered as-is to the page:

<div id="cka">
<%=raw @formatted_question[:anno_a] %>
</div>

Note the ERB tag begins "<%=raw" That 'raw' is http://apidock.com/rails/ActionView/Helpers/OutputSafetyHelper/raw and will send the actual contents, i.e., the HTML, to the page.
