What problems are you talking about that need the answers?
Remember when you are rounding, you go the place behind whatever you are rounding to. If that digit is 4 or less you round "down" so if it was 6.25 needing rounded to the nearest whole number, you would round to 6 because the tenths place has a 2, and 2 is less than 4. If your number was 6.5 going to the nearest whole number you would round up to 7, because 5 or more rounds up. Hopefully that helps :)
