@beebzzz,
they certainly do look a bit like percentages, with neither of the numbers in each set over 100. the only thing I'd note is that if they are percentages, all of the numbers on the left of the decimal are under 35, which seems a bit odd.
edit: it's also important to note that the conundrum specifically says, "decipher the following clue," indicating we should be working on some sort of cipher, yes?
