FAQs on Estimating to nearest Hundreds by Rounding off Video Lecture - Mathematics (Maths) Class 6

1. What is rounding off to the nearest hundreds?
Ans. Rounding off to the nearest hundreds means approximating a number to the closest whole number with two zeros at the end. For example, rounding off 543 to the nearest hundreds would give 500, while rounding off 712 to the nearest hundreds would give 700.
2. How do you round off a number to the nearest hundreds?
Ans. To round off a number to the nearest hundreds, you need to look at the digit in the tens place. If it is 0-4, then the hundreds digit remains the same. If it is 5-9, then the hundreds digit is increased by 1. All the digits after the hundreds place are dropped. For example, rounding off 745 to the nearest hundreds would give 700.
3. Can you provide an example of rounding off to the nearest hundreds?
Ans. Sure! Let's say we have the number 1,837. To round it off to the nearest hundreds, we look at the digit in the tens place, which is 3. Since it is less than 5, the hundreds digit remains the same. Therefore, rounding off 1,837 to the nearest hundreds gives us 1,800.
4. What happens when the number to be rounded off ends in 50?
Ans. When the number to be rounded off ends in 50, the rule is to round up to the nearest even number. This is called "round half even" or "banker's rounding." For example, if we have the number 1,650 and we want to round it off to the nearest hundreds, it would be rounded to 1,600.
5. Is rounding off to the nearest hundreds the same as rounding off to the nearest thousand?
Ans. No, rounding off to the nearest hundreds and rounding off to the nearest thousand are different. Rounding off to the nearest hundreds means approximating a number to the closest whole number with two zeros at the end, while rounding off to the nearest thousand means approximating a number to the closest whole number with three zeros at the end. The digit in the thousands place is considered for rounding off to the nearest thousand.
