Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Rhind Mathematical Papyrus contains, among other mathematical contents, a table of Egyptian fractions created from 2/n. The text reports 51 rational numbers converted to short and concise unit fraction series. The document was written in 1650 BCE by Ahmes. Aspects of the document may have been copied from an unknown 1850 BCE text. Another ancient Egyptian papyrus containing a similar table of Egyptian fractions, the Kahun Papyrus, written around 1850 BCE is about the age of one unknown source for the Rhind papyrus. The Kahun 2/n table differs in minor respects to the Rhind Papyrus'' 2/n table.
