A whole can be divided into any number of parts.

The golden rule for fractions is that the parts must be equal.

2, 3, 4, 5, 6… 10… 50… 100… 200… any number!

The total number of equal parts becomes the bottom part of the fraction.

It is called the DENOMINATOR

For example:

Denominator = 4 Denominator = 8© Teachable and Nitu Duggal. Some rights reserved. http://teachable.net/res.asp?r=929

The number of parts that are referred to becomes the top part of the fraction.

It is called the NUMERATOR

For example: When we refer to striped parts

Numerator = 3 Numerator = 1© Teachable and Nitu Duggal. Some rights reserved. http://teachable.net/res.asp?r=929

So a fraction is written as:

Number of parts referred (NUMERATOR)

Total number of parts of the whole (DENOMINATOR)

•A fraction is part of a whole.

•All parts in a fraction are equal.

•A fraction has a Denominator which is written in the bottom. It represents the total number of parts of the whole.

•It has a Numerator which is written on the top. It represents the number of parts that are being referred to out of the total parts.
