They're not numbers, not with the commas in them. You can't divide formatted
strings.
When asked to treat strings as numbers, PHP reads as much of the data until it
stops matching basic numeric format, so you're actually getting 3/5 which is
0.6.
Remove the commas; only add them back in again when formatting them for
display.
