To round to the nearest hundred, look at the hundreds place (8 in 2847). The digit to the right of it (the tens place) is 4. Apply the rounding rule: if the digit is less than 5, round DOWN (keep the hundreds digit the same); if it's 5 or more, round UP (increase the hundreds digit by 1). Since 4 < 5, we round down. The 8 stays as 8, and all digits to the right become 0. Therefore, 2847 → 2800. This type of rounding is essential for estimation questions in ECZ examinations.
