To determine if 455 + 229 is more than 650, we can use compatible numbers.
Compatible numbers are numbers that are close to the original numbers and easy to work with.
In this case, we can use 450 as a compatible number for 455 and 230 as a compatible number for 229.
So the compatible numbers would be:
455 → 450
229 → 230
Now we can add the compatible numbers:
450 + 230 = 680
Since 680 is greater than 650, we can conclude that 455 + 229 is indeed more than 650.
