# What is Numerator Mean in Math?

The numerator is the number written on the top of a **fraction** bar. It indicates the number of parts taken out of the whole. So anything that is above the fraction bar is the numerator. In this article learn more about the numerator.

**What is a Numerator?**

Every fraction has two parts, a numerator, and a **denominator**. The numerator is the top part of a fraction bar, and the denominator is the bottom part of a fraction bar. Remember that a fraction indicates a part of a whole. The numerator denotes how many parts of that whole are being considered, while the denominator indicates the total number of parts of the whole.

A fraction is written in the form a/b, where a is the numerator, and b is the denominator. So, we can say that a fraction is written as Numerator/Denominator.

**Numerator in division **

A fraction written in the form a/b is basically a ÷ b. It means we divide a by b. For example, 1/2 is the same as 1 ÷ 2. It means how many 2’s are there in 1’s. Here, 1 can be considered as the dividend or as a numerator, while 2 can be considered as the divisor or the denominator.

**The numerator in a fraction**

Fractions can be classified into various types based on the numerators. Some of the different **types of fractions **are as follows:

- When the numerator is greater than or equal to a denominator is called an improper fraction
- When the denominator is greater than a numerator is called a proper fraction
- When the numerator is 1 is called a unit fraction
- When the numerator of a fraction is 0, the complete fraction becomes 0. It doesn’t matter what the denominator is, if the numerator is zero, then the complete fraction is zero. For example: If we have 0/3 then we will get 0 as the simplified form.
- If both the numerator and denominator are the same, then we get 1 as the simplified form. Example, 5/5 = 1

**Numerator vs. Denominator**

The numerator and denominator together make a fraction.

Numerator | Denominator |

It is at the top of the fraction bar. | It is below the fraction bar. |

The numerator denotes the number of parts taken out of the whole. | The denominator indicates the total number of equal parts in which the whole is divided. |

Example: In 5/7, 5 is the numerator. | Example: In 5/7, 7 is the denominator. |
