Fractional unit is a mathematical term. Divide the unit "1" into several parts, and take one part, which is called decimal unit. That is, the numerator is 1, and the denominator is a positive integer fraction, also called unit fraction, which is called 1/n, and the unit fraction is also called "monomolecular fraction" and "Egyptian fraction".

brief introduction

General fractions are calculated by converting fractions with different denominators into numbers with the same decimal unit.

For example, the decimal unit of one eighth is one eighth, and so on.

Fractions are equal in size, but the fractional units are not necessarily equal. If two eighths equals a quarter, a quarter has a large decimal unit.

The maximum number unit is half, and there is no minimum number unit.
