Hence, is nearer to than We see the digit in the ones place is 1, now round to the nearest multiple of 10 which is smaller than the number. We see the digit in the ones place is 5, now round to the nearest multiple of 10 which is greater than the number. We choose the two multiple of 10 just greater than and just less than 14,57, on the number line. While rounding off to the nearest hundred, if the digit in the tens place is between 0 — 4 i.
