What is a Fraction?
A fraction shows a part of a whole.
Written as numerator / denominator.
Numerator ³ number of equal parts 
taken.
Denominator ³ total number of 
equal parts in the whole.
Visualising Fractions
Fractions can be shown by shading shapes or using fraction kits.
The triangle is cut into 
3 equal parts. 1 part is 
shaded 
ó 1/3
The circle is cut into 8 equal slices. 3 slices 
are shaded 
ó 3/8
The square is cut into 4 equal 
boxes. 1 box is shaded 
ó 1/4, called a quarter. Four 
quarters make one whole.

Equivalent Fractions
Two fractions are equivalent if they represent the same value or proportion.
Example: 1/2 = 2/4 = 3/6
Rule: Multiply or divide both numerator and denominator by the same number to get an equivalent fraction.
Example: 3/5 × (2/2) = 6/10

Types of Fractions
1. Like Fractions
 Fractions with the same denominator.
Example - 1/5, 2/5, 3/5
2. Unlike Fractions
Fractions with different denominator.
Example - 2/3, 3/5, 2/7.
