When rounding a number to the nearest hundred you look at the number in the hundreds place, in this case it the digit 7. To decide if you will be rounding it up to 8, or leaving it at 7 you need to look at the digit to the right of it, in this case there is an 8 in the tens place. It that digit is a 5 or greater you round up, if that digit is a 4 or less you leave it as it is.
