Old Egyptian Fractions at MathCats

(Web and android version)

Old Egyptian Math Cats knew fractions like 1/2 or 1/4 (one piece of a pie). But to make fractions like 3/4, they had to add pieces of pies like 1/2 + 1/4 = 3/4. Old Egyptian Math cats never repeated the same fraction when adding. They never wrote: 1/4 + 1/4 + 1/4 = 3/4

How it works:

Choose puzzles from the list on the top. ( * = easier, **** = very hard.) Add 2 or 3 fraction pieces below. After you find one solution, the puzzle is marked "Solved." Can you find more solutions? (Click to see them listed on the bottom.)
