If you have a look at these fractions you will see they are all the same amount. We say they are equivalent fractions.
Example:
1/4 = 3/12 = 5/20
2/4 is the same as 2 lots of 1/4
2/4 of 8 = 4/8
(1/4 of 8 is 2/8. 2 lots of 1/4 of 8 is 2/8 + 2/8 = 4/8)
3/4 is the same as 3 lots of 1/4
3/4 of 12 = 9/12
(1/4 of 12 is 3/12. 3 lots of 1/4 of 12 is 3/12 + 3/12 + 3/12 = 9/12)
If you divide the bottom number (denominator) by the top number (numerator) and it equals 4, then the fraction is the same as one-quarter (1/4).
When the top number (numerator) is one-fourth of the bottom number (denominator) the fraction is a quarter.
