Who is the founder of fraction?

Answer 1

From as early as 1800 BC, the Egyptians used fractions. There fractions were special because they all had numerator of 1. This is called a unit fraction. So a fraction such as 3/4 was written as 1/2 + 1/4. Fractions the way we use them now were first used in the 17th century in Europe. It is hard to really say who founded fractions since many of the early reference like the one for the Egyptians and Babylonians were fractions but not like the ones we use now.
