title: Find two numbers in string with Ruby using Regex
body: <p>I have a string that looks like this:</p>
  
  <p>Results 1 - 10 of 20</p>
  
  <p>How would I find the number 10 and 20 of that sentence using regex in Ruby?</p>
  
  <p>Something like:</p>
  
  <pre><code>first_number, second_number = compute_regex(my_string)...
  </code></pre>
  
  <p>Thanks</p>
