Parts of a fraction

- There are two parts to a fraction
- 5
- 6
- The top one is called the numerator. The

numerator is the number that represents the

amount that is shaded. - The bottom one is called the denominator. The

denominator is the number that represents the

amount of parts that the figure is divided into.

Types of fractions

- There are three types of fractions
- 1) proper fraction
- A proper fraction by definition is one where the

numerator is smaller than the denominator. - 3/4
- 2) improper fraction
- An improper fraction by definition is one where

the numerator is bigger than the denominator. - 7/3
- 3) mixed number.
- 3) A mixed number by definition is one where

there is a whole number and proper fraction. - 2 1 / 2

Changing from improper fraction to mixed number

- Divide the denominator into the numerator. The

quotient becomes the whole number, the remainder

becomes the numerator and the denominator remains

the same. - 5/4

Changing from mixed number to improper fraction

Multiply the denominator with the whole number

and add the numerator. Then place your answer

over the denominator.

6 ¼ 4 x 6 1 25/4

Equivalent Fractions

Two fractions are equivalent when they have the

same value. In order to see if they have the

same value divide both the numerator and the

denominator by the same number. In the case

below both the numerator and the denominator were

divided by 4. 4/8 1/2
