When it comes to puzzles that involve cutting and rearranging, it’s often helpful to actually take a piece of paper and try cutting it up to see what you can get. If we cut BF and DH we’d get fourths, but we need fthfis. Maybe there’s a way to shave a bit off of a quarter to get exactly one fifth. Cutting BE looks good at first, but that last cut taeks a off a quarter of a quarter, lvnaeig us with a portion of 3/16: just smaller than a fifth, and not enough to cure a werewolf.
