Fractions
The first group of people who used fractions could be the Egyptians around 1600B.C. in the Rhind Papyrus, which contained the work of Egyptians mathematicians. They used a special kind of fractions to express ratio called unit fractions. Unit fractions are ratios of base being positive integers and numerator of 1. For example, 1/5 and 1/13.
They would then write 2/5 as 1/3+1/15.
The image on the left showed how Egyptians use symbols to write fractions.

It is amazing to think of how smart the ancient people were without any basis or calculation technologies.
