The first thing we tried was to write a list of the multiples of 3 and 4 and tried to match them up, we tried 12 because both 4 and 3 go into 12 but that didn't work. Then we realized it had to be bigger than 12 because you cant let the quarter get too big (compared to the number) and become more than one third, so then we experimented with a couple of numbers and finally landed on 24.

So there was 24 coins on the table and 6 had the heads shown we flipped 2 of the tails over and that made 8 which is 1 third of 24.
