What is a Fraction?
Fractions are a small part or item forming a piece of a whole.
Example:
Let's break a hexagon into 6 equal pieces.
What if we took one of the pieces? That would be 1 piece out of 6 pieces, right?
Below is an example of how you would write the fraction. We read this by saying "one sixth".
A fraction has a numerator and a denominator.
The numerator tells you how many of those pieces you have.
The denominator tells you how many total pieces there are.
Numerator
––––––––––
Denominator
- All, everything, total amount
- All of the parts
The pizza to the left is divided into 8 equal parts.
What fraction of the pizza has pepperoni on it?
If you said all of it, you are right!
8 pieces out of 8 total pieces have pepperoni. So the fraction would be..
8
–– OR 1 whole pizza
8
When the numerator and denominator are the same, it is the same as one whole, or 1.
An object divided into two equal parts has two halves.
The circle to the left is divided into halves.
The red portion of the circle is 1 of 2 halves, or one half. This is written as
1/2
Both the red and blue pieces together make 2 of 2 halves. This is written as
2/2
Thirds
When an object is divided into three equal parts it is divided into thirds.
The circle below is divided into three equal parts.
If you took one piece of the circle, you would have 1/3 or one third.
With one piece gone, there are two pieces left. The remainder of the circle is 2/3 or two thirds.
