Well, I suppose we could work something out using analytical functions. But why do you want this?

Here's an example; see if you can use it.

Create two queries: first will select count of employees who work in department 10:

select count(*) c1 
from emp 
where deptno = 10

The second query will return number of employees in department 20, along with the ratio value you need to display:

select count(*) c2, 
       count(*) / :c1 c_divide_c2_by_c1  --> this is what you are looking for
from emp 
where deptno = 20

Use Report Wizard to create a paper layout. The final result is as follows:
