i'd say that 6300 is greater than 530
i'd also say the 530 is less than 6300
i'd also say 6300 is 11.88679245 . . times greater than 530
and that 530 is 0.0841269841 times as great as 6300
i'd say that 530 has a 3 in it and so does 6300, except that the 3 in 530 is in the tens place, and the 3 in 6300 is in the hundreds place
i'd say . . . . (on and on I could go)
when you say "compare", be specific
