A fraction (or polynomial) denotes the proportion of two expressions in mathematics (ie a fraction indicates division) and can be used to write any rational number.
A fraction contains a fraction line above which is the numerator and below which is the denominator, with both the numerator and denominator being integers.
- numerator – how many parts of the whole we will take
- fraction line – means share
- denominator – how many equal parts we divide the whole into.
