   Problems 1–7, 7B and 8–40 are concerned with arithmetic and elementary algebra. Problems 1–6 compute divisions of a certain number of loaves of bread by 10 men and record the outcome in unit fractions. Problems 7–20 show how to multiply the expressions 1 + 1/2 + 1/4 = 7/4, and 1 + 2/3 + 1/3 = 2 by different fractions.

   [8] Many similar problems of division into fractions are known from mathematics in the medieval Islamic world, [1] [4] [9] but "it does not seem that the story of the 17 camels is part of classical Arab-Islamic mathematics". [9] Supposed origins of the problem in the works of al-Khwarizmi, Fibonacci or Tartaglia also cannot be verified. [10]

   Width: 3.8 to 7.6 cm (1.5 to 3 in) The Moscow Mathematical Papyrus, also named the Golenishchev Mathematical Papyrus after its first non-Egyptian owner, Egyptologist Vladimir Golenishchev, is an ancient Egyptian mathematical papyrus containing several problems in arithmetic, geometry, and algebra. Golenishchev bought the papyrus in 1892 or 1893 ...

   But the last copy of 1/64 was written as 5 ro, thereby writing 1 = 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64 + (5 ro). These fractions were further used to write fractions in terms of / terms plus a remainder specified in terms of ro as shown in for instance the Akhmim wooden tablets. [2]

   Finally, there were nine sums, having odd denominators, converted from Egyptian fractions: 2/3, 1/3 (twice), 1/5, 1/7, 1/9, 1/11, 1/13 and 1/15. The British Museum examiners found no introduction or description to how or why the equivalent unit fraction series were computed. [4] Equivalent unit fraction series are associated with fractions 1/3 ...

7. Fraction - Wikipedia

   en.wikipedia.org/wiki/Fraction

   A unit fraction is a common fraction with a numerator of 1 (e.g., ⁠ 1 / 7 ⁠). Unit fractions can also be expressed using negative exponents, as in 2 −1, which represents 1/2, and 2 −2, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two, e.g. ⁠ 1 / 8 ⁠ = ⁠ 1 / 2 3 ⁠.

   Slices of approximately 1/8 of a pizza. A unit fraction is a positive fraction with one as its numerator, 1/ n.It is the multiplicative inverse (reciprocal) of the denominator of the fraction, which must be a positive natural number.

9. Egyptian fraction - Wikipedia

   en.wikipedia.org/wiki/Egyptian_fraction

   An Egyptian fraction is a finite sum of distinct unit fractions, such as That is, each fraction in the expression has a numerator equal to 1 and a denominator that is a positive integer, and all the denominators differ from each other. The value of an expression of this type is a positive rational number ; for instance the Egyptian fraction ...
