## Description

This is the android version of the Mathcats Old Egyptian Fractions:

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

In ancient Egypt, they wrote fractions with numerator 1 or as a sum of fractions with numerator 1. So the fraction 2/3 would be 1/2 +1 / 6. It has a certain logic if we consider a particular case: if we divide two loaves among three people will give each bread half (1/2) and a third of the bread is left half (1/6).

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.)
