Rails How to Calculate Time Difference with an Integer from 3 Dates

Question

How to compare 3 dates, (Time.now - @ model.updated_at) <: integer (converted to days). So, first this is an expression between two dates, and the difference between two dates like (amount of time) is compared (<less) with: integer.days (amount of time). Hope this makes sense ... I'm looking at different options, but I'm just getting more confused. Thanks for any help.

"#{Time.now}".to_i.days - "#{:updated_at}".to_i.days < "#{:integer}".to_i.days
