Greater. The place value is to the right more then the other number making it greater.
To clarify 6.24 is bigger then .624
For example lets say you had 6.00 Apples. Thats 6 whole apples!
Then let's say you had 0.600 Apples. Thats only half an apple!
So 6.00 Apples would be more. Thats why 6.24 is bigger.
