Egyptian Fractions - Writing them all; Egyptian Fractions - Writing them all. 7. 4 places!!! When a fraction had a numerator greater than 1, it was always replaced by a sum of fractions â¦ The egyptians also made note of the fraction They wanted to write any rational between 0 and 1 as a sum of such âunitâ fractions. Although they had a notation for 1 / 2 and 1 / 3 and 1 / 4 and so on (these are called reciprocals or unit fractions since they are 1 / n for some number n), their notation did not allow them to write 2 / 5 or 3 / 4 or 4 / 7 as we would today. These are unit fractions â fractions whose numerator is one. Here are some egyptian fractions:1/2 + 1/3 (so 5/6 is an egyptian number), 1/3 + 1/11 + 1/231 (so 3/7 is an egyptian number), 3 + 1/8 + 1/60 + 1/5280 (so 749/5280 is an egyptian â¦ met the African, and the Egyptians at least since 4000BC in Egypt.
