Egyptian fraction expansion
Webrestriction leads to complicated expressions even for many fairly simple fractions, and the discussion and tables on page 40 of Burton give expansions for a long list of fractions with small denominators. As noted on page 43 of Burton, every rational number between 0 and 1 has an Egyptian fraction expansion of this type.

Weban Egyptian fraction expansion is the representation of a rational number as a sum of distinct unit fractions (see [3]). Note that for the Egyptians, the basic fractions were the unit fractions and the special fraction . The Rhind papyrus (2000-1800 B.C.) gives an algorithm for representing rational numbers as sums of these basic fractions [7]. WebJun 1, 2024 · In the authors' earlier work, the SEL Egyptian fraction expansion for any real number was constructed and characterizations of rational numbers by using such expansion were established.

WebEngel expansion, sometimes called an Egyptian product, is a form of Egyptian fraction expansion in which each denominator is a multiple of the previous one: In addition, the sequence of multipliers ai is required to be nondecreasing. Every rational number has a finite Engel expansion, while irrational numbers have an infinite Engel expansion.
