New and Old Ahmes Papyrus classifications,

Ahmes scaled 3/53, 5/53, 15/53 by LCM 20, 12, 4 to 60/1590, 60/636 and 60/212, resp. Red number numerator (53 + 4 + 2 + 1) = 60 defined each unit fraction series. D/2 = radius and 256/81 = pi in area(A) = [(8/9)(D)]^2 cubit^2, and volume(V) = (2/3)(H)[(4/3)(D)]^2 khar formulas; 1500 khar x 1/20 =(75) x 400-hekat; 4 x 100-hekat x 1/70 = [(6400/64)/70]4-hekat =[(64 + 16 + 8 + 2 + 1)/64]4-hekat + (150/70)4-ro generalized a (64/64)/n = quotient (Q/64)hekat + remainder (5R/n)ro were used.
