Two queries without join

[aRaGaR]

Hello all,
Broadly speaking - I have two queries which give me two numbers (totals) and I want just to show the division of these two numbers. I know one way is to join (or union) the two queries in new one and this way to get the numbers. Is there any other way without joining, unioning etc, because it seems a little slow for such a simple calculation? Is there some way to store the values in something like a variable and to use it later?
Thank for the help in advance

U can unlock the list and use Singletons in your report and associate the query to them as the query would only give you one grand total
