Explain how to find which is greater 1/4 of 12 or 1/3of 12

1/3 of 12. This is because if you divide 12 by three, then you get a greater number than when you divide 12 by four.

Well to find a fourth of 12 you need to divide 12 by 4

12:4=3

and to find a third of 12 you need to divide 12 by 3

12:3=4

so now you need to figure out which is greater 4 or 3?

(that should be easy but if not the answer is 4 so 1/3 of 12 is greater than 1/4 of 12)
