Maths for year 4 students

Today we are going to conitnue so we can understand better what equivalent fractions are.

Let's remember:

What is a fraction?
A fraction represents a part of a whole.

What are equivalent fractions?
Equivalent fractions are fractions with different numbers that show the same part of a whole. They have different numerators and denominators, but the fractional values are the same.

Equivalent Fractions have the same value, even though they may look different.

These fractions are really the same:

12  =  24  =  48

Why are they the same? Because when you multiply or divide both the top and bottom by the same number, the fraction keeps it's value.

The rule to remember is:

"Change the bottom using multiply or divide,

And the same to the top must be applied"  

Here is why those fractions are really the same:

    × 2            × 2 

   

1	=	2	=	4
2		4		8

	× 2		× 2

And visually it looks like this:

1/2

=

2/4

=

4/8
