Answer

Value after rounding off to the nearest hundred is = 14.3 Value after rounding off to thousandth digit is = 14.27

Work Step by Step

14.26841 For nearest hundred The digit in the hundredth place place is 2. If the digit next to the hundredth place is 5 or more than 5 then hundredth place digit is increased by 1, and if not then it remains the same and the digits after that are dropped. In this case the digit next to hundredth place is 6, therefore hundredth place digit becomes 3. Value after rounding off to the nearest hundred is = 14.3 For nearest thousand The digit on thousandth place is 6. The digit next to that is 8 which is more than 5, therefore thousandth place digit becomes 7. Value after rounding off to thousandth digit is = 14.27
