this is easy they already have the same denominators (the bottom number)
so lets set this up
4 5
--- or ---
3 3
all we need to do here is figure out if 4 is bigger or 5.
im sure you know how to count right?
1, 2, 3, 4, 5,
5 comes after four that means 5 is bigger!
so our fraction
5
---
3
is bigger.
I hope this helps you:)
