title: Can I reasonably split these number strings?
body: <p>I have a bunch of strings like so:</p>
  
  <pre><code>x  &lt;-  c("4/757.1%", "0/10%", "6/1060%", "0/0-%", "11/2055%")
  </code></pre>
  
  <p>They're fractions and the percent value of said fractions that somehow somewhere got mushed together. So the meaning of the first number in the example is 4 out of 7 is 57.1%. I can easily get the first number before the /(with, say, <code>stringr::word(x, 1, sep = "/")</code>) but the second number can be either one or two characters long so I'm having trouble thinking of a way to do it. I don't need the % value since that is easy enough to recalculate once I get the numbers.</p>
  
  <p>Can anyone see a way of doing it?</p>
