given a ratio (ex. 374:266 or 724.36292:740.37872) how do I get the smallest ratio? 187:133 for the first ex. Now for the second ex, that is a tricker answer. Do I convert to integer and then calculate the smallest ratio? I think I am leaning that way.
Also, 187:133 seems a bit large. Next question is how to identify a smaller ratio that is "close"? say within 2 or 3 decimal places? this example ratio is about 1.4060:1 or I guess I could say 14.06:10 then about 7:5? Not sure if I'm even close to the right track on this.
Be nice if there were already a gem that did this calculation. But I can write a method once I find a correct algorithm. I've tried google searching, but keep getting either web pages that do a Ratio Simplifier or things about gem stone ratios.
NOTE: this is not for Rails. It is for a process that I'm writing. Will be ran on my mac locally only.

return nil if x.nil? or y.nil?
x = x.round

puts ratio_simplifier 374, 266
Thanks for any insight
