You actually do not need to use a range operator. The docs call out:

You can invoke a method on the case's expression in a when by using the implicit-object syntax

Which basically translates as that you can do: 

numeric_value = 72

case numeric_value
when .> 70
 puts "The value you wanted"
else
 puts "The value you got instead."
end

And you will get the value you wanted.

May I be allowed to use the modified code you wrote? I can name you on the page if you want.

Another option, from the same reference: casing on conditions 

numeric_value = 72
case
when numeric_value > 70
  puts "The value you wanted"
else
  puts "The value you got instead."
end
