What are equivalent fractions?
If you have a look at these fractions you will see they are all the same amount. We say they are equivalent fractions.
1/2 = 2/4 = 4/8. They are all half.
When the top number (numerator) is half of the bottom number (denominator) the fraction is a half.
If you divide the bottom number of a fraction by the top number and it gives 2, the fraction is equivalent to 1/2.
