Rails - Mar 2006 - basic operations in rails

Hi all,
This must be such a beginner''s problem, but I can''t figure it
out.

I''m pulling two integers out of a database, and i want to divide one 
value with the other, but i keep getting an error about operating on 
strings.
Here''s the code -

low_freq = unsorted.last.freq
high_freq = unsorted.first.freq
divider = high_freq / low_freq


In my view, if i display the contents of low_freq or high_freq there is 
indeed an integer in there.

Can someone help a newb?

cheers

try this

low_freq = unsorted.last.freq.to_i
high_freq = unsorted.first.freq.to_i
divider = high_freq / low_freq
