About the application:

The apk proposes 31 challenges to overcome. Build the proper fractions listed at the top of the application, adding two, three or four unit fractions. Each proposed proper faction has a variable number of solutions. And various levels of difficulty You can not repeat unit fractions with the same value. In the apk you'll search a button to delete all the solutions found in the current trouble, and to begin from scratch. The littlest unit fraction used in this apk is 1/66. The tool is designed to present the usefulness of the subtraction of fractions in solving such problems. From www.nummolt.com This is an evolution of the "Old Egyptian Fractions" created in collaboration with www.mathcats.com Hint: In the Rhind Mathematical Papyrus (RMP) in 1650 BC the scribe Ahmes copied the now-lost try from the reign of the lord Amenemamhat III . The first part of the papyrus is taken up by the 2/n table. The fractions 2/n for odd n ranging from 3 to 101 are expressed as sums of unit fractions. In this apk you can build some of the Ahmes decompositions ( 2/3 , 2/5, 2/7, 2/9, 2/11 ) and the discarded ones by him also. The apk let to decompose also: 3/4 , 3/5 , 4/5 , 5/6 , 3/7 , 4/7 , 5/7 , 6/7 , 3/8 , 5/8 , 7/8 , 4/9 , 5/9 , 7/9 , 8/9 , 3/10 , 7/10 , 9/10, 3/11, 4/11, 5/11, 6/11, 7/11, 8/11, 9/11, and 10/11. You can use the knowledge acquired solving the 2/n decompositions to solve the rest of the problems. The apk warns of obtaining the best solution (the one with the lowest denominators) If it's one of the issues appearing in the Rhind Mathematical Papyrus table, the apk warns of coincidence with the solution written in the Rhind 2/n table.
