Book III
The third part of the Rhind papyrus consists of a collection of 84 problems. Problem 61 consists of 2 parts. Part 1 contains multiplications of fractions. Part b gives a general expression for computing 2/3 of 1/n, where n is odd. In modern notation the formula given is
Problems 62- 68 are general problems of an algebraic nature. Problems 69 - 78 are all pefsu problems in some form or another. They involve computations regarding the strength of bread and or beer.
Problem RMP 79' sums five terms in a geometric progression. It is a multiple of 7 riddle, which would have been written in the Medieval era as, "Going to St. Ives" problem. Problems 80 and 81 compute Horus eye fractions of henu (or hekats). Problem 81 is followed by a table. The last three problems 82 - 84 compute the amount of feed necessary for fowl and oxen.
