I think it could be helpful to be clearer with the suggestions!

Did you ever find any helplful resources? :)

Yep, Ruby version had a small bug: hopefully fixed and thanks for the inconvenience :)

Where can I go to learn more about how to speed code up? It would be great if helpful resources were pointed out! Cheers!

Jake listened to your prayers and the kata was thus upranked :)

Hi! That's correct as well. ^^ This kata didn't require class vars though.

Cheers. And in Ruby you also use @@ when declaring class variables!

In Ruby '$' symbol is used for defining global vars. You use '@' when declaring instance variables.

Well, proposal for a discussion about ranking in general submitted, if anyone feels like contributing :)

Hey Giacomo, can you please align the random tests in your translations with the ones in my Python test fixture? I did several blocks for those for a reason - they cover many corner cases.

Giacomo, I think you have a bug in your reference solution in Ruby - it does not add the sign to fractions that have no integer part. Please correct this.

Specify the language please. I suspect it is Ruby. I don't know much about Ruby, let's wait for Giacomo, he translated this.

Is this a fixable error?

Testing for -1/4
It should work for random inputs too - Expected: "1/4", instead got: "-1/4"

It looks like the random test cases lose the negative signs?

Oh, I see. And I was not notified on this, sorry for the delay: gladly approved :)
