Fraction originally refers to a part of the whole, or more generally, to any equal number of parts. The form of expression is the ratio of integer A to integer B (whether a false score in multiples of b is a score is controversial).

Fraction indicates the fraction of one number to another, or the ratio of one event to all events. Divide the unit "1" into several parts on average, and the number representing such a part or parts is called a fraction. The numerator is above and the denominator is below.

When the denominator is 100, it can be written as a percentage.

The earliest fraction was the reciprocal of an integer: an ancient symbol representing one-half, one-third, one-quarter and so on. Egyptians used the Egyptian score of 1000 BC. About 4000 years ago, Egyptians separated with slightly different scores.

They use the least common multiple and unit fraction. Their method gives the same answer as the modern method. Egyptians also have different representations of Akhmim wood chips and the second generation of mathematical papyrus.

The Greeks used unit fractions and (post) continuous fractions. The Greek philosopher Pythagoras (about 530 BC) found that two square roots cannot be expressed as part of an integer. ?

Among 150 Indians in India, Jain mathematicians wrote "Sthananga Sutra", which includes number theory, arithmetic operation and operation.
