r.to_s is equal to "#{r}", but more straightforward. So when you want to
convert something to a string, it is better to use its to_s method.

The puts method, though, invokes the to_s method on the object before it
outputs it. So when you are sending an object to puts, you don't need to
worry about whether it is a string at all.

puts "#{r}"   # so rather than this
puts r        # instead use this
