Concept:Rounding to the nearest hundred means looking only at the tens digit to decide whether the hundreds digit increases or stays the same.Explanation:Consider the number 48,947.2547.Identify the hundreds place: in 48,947.2547, the hundreds digit is 9.Now look at the digit immediately to its right, which is the tens digit: 4.Since 4<5, the hundreds digit is kept as 9, not increased.Replace the tens and ones digits with zeros, and drop the decimal part because we are rounding to a whole-number place.So 48,947.2547 becomes 48,900.This is confirmed because 48,947 is only 47 away from 48,900, but 53 away from 49,000.Answer:48,900, which is option B.
