To round to the nearest hundred, you first consider only digits at place value hundreds or greater. In this instance, that would be 7,900. The next step is to consider the tens value. If it is 5, 6, 7, 8 or 9 you would round up. Otherwise, you would leave the number as it is (round down). In this case, the tens digit is 9, and so we round up. Thus, 7,999 rounded to the nearest hundred is 8,000.
