In this section, we ask what is the fraction definition? We have seen that whole numbers allow us to describe or count a number of objects. Integers allow us to expand
on the whole numbers and consider negative values. A fraction is defined as being used to describe a part of a whole amount. For an easy example, most people use a pizza.
Suppose the pizza is cut up into 5 equal slices. After 2 slices of the pizza are eaten, we can say that we have 3 slices of the pizza remaining out of a total of 5 slices.
This can be represented with the fraction:
$$\frac{3}{5}$$
The 3 represents the number of equal parts remaining, this is known as the numerator. The numerator displays the number of parts under consideration (being used or
discussed). The 5 represents the total number of equal parts, this is known as the denominator. The horizontal bar that sits between the 3 and 5 is known as a fraction bar,
this separates the numerator from the denominator.

Example 1: Identify the Numerator and Denominator $$\frac{2}{3}$$ The 2 is the numerator, this is the top number

The 3 is the denominator, this is the bottom number

This fraction represents 2 parts out of a total of 3.

We will also discuss the types of fractions that we will encounter. In most cases, we will deal with a proper fraction. We will also come across improper fractions, and mixed numbers.

- Proper Fraction
- Used to describe a fraction quantity whose value is less than one, this occurs when the numerator is less than the denominator

- Improper Fraction
- Used to describe a fraction quantity whose value is one or larger, this occurs when the numerator is greater than or equal to the denominator

- Mixed Number
- Used to describe the sum of a whole number and a proper fraction
