Egyptian fraction - Wikipedia
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.

An Egyptian fraction is the sum of finitely many rational numbers, each of which can be expressed in the form \(\frac{1}{q},\) where \(q\) is a positive integer. For example, the Egyptian fraction \(\frac{61}{66}\) can be written as \(\frac{61}{66} = \frac12 + \frac13 + \frac{1}{11}.\)
One of the most exciting concepts in Egyptian mathematics is the Egyptian fraction. Fractions used in Ancient Egypt didn’t follow the same structure as the fractions we use today; the value of the numerator was limited only to 1 [2]. How, then, would they go about representing a number such as 7 without using a vulgar fraction?
