11. It has been noted that there are groups of unit fraction decompositions in the EMLR which are very similar. 12. The scribe practiced conversions of rational numbers 1 / p and 1 / pq to alternative unit fraction series. 13. These tables allowed the scribes to rewrite any fraction of the form \ tfrac1n as a sum of unit fractions . 14. The British Museum examiners found no introduction or description to how or why the equivalent unit fraction series were computed. 15. Arthur Eddington argued that the fine structure constant was a unit fraction , first 1 / 136 then 1 / 137. 16. The Egyptian Mathematical Leather Roll for instance is a table of unit fractions which are expressed as sums of other unit fractions. 17. The Egyptian Mathematical Leather Roll for instance is a table of unit fractions which are expressed as sums of other unit fractions . 18. Drini claims an awareness of mathematics which he often fails to evidence as in the discussions in unit fractions and circle squaring. 19. In the 21st century, Ahmes is becoming clearly reported by converting vulgar fractions into optimized unit fractions series within a LCM method. 20. Equivalent unit fraction series are associated with fractions 1 / 3, 1 / 4, 1 / 8 and 1 / 16.
