FAQs on Examples: Rounding off to nearest tens and Hundreds Video Lecture - Class 6

1. How do you round off a number to the nearest tens place?
Ans. To round off a number to the nearest tens place, you look at the digit in the ones place. If it is 5 or greater, you increase the tens digit by 1. If it is less than 5, you keep the tens digit as it is. For example, if you want to round off 46 to the nearest tens place, since 6 is greater than 5, the tens digit becomes 5, resulting in 50.
2. How do you round off a number to the nearest hundreds place?
Ans. To round off a number to the nearest hundreds place, you look at the digit in the tens place. If it is 5 or greater, you increase the hundreds digit by 1. If it is less than 5, you keep the hundreds digit as it is. For example, if you want to round off 346 to the nearest hundreds place, since 4 is less than 5, the hundreds digit remains 3, resulting in 300.
3. What happens if the digit in the ones place is exactly 5 when rounding off to the nearest tens place?
Ans. When the digit in the ones place is exactly 5, and you are rounding off to the nearest tens place, you look at the digit in the tens place. If it is even, you keep the tens digit as it is. If it is odd, you increase the tens digit by 1. For example, if you want to round off 65 to the nearest tens place, since 6 is even, the tens digit remains 6, resulting in 70.
4. Can you round off decimal numbers to the nearest tens and hundreds place?
Ans. Yes, you can round off decimal numbers to the nearest tens and hundreds place. The process is the same as rounding off whole numbers. For example, if you want to round off 73.6 to the nearest tens place, since 6 is greater than 5, the tens digit becomes 4, resulting in 70. If you want to round off 73.6 to the nearest hundreds place, since 3 is less than 5, the hundreds digit remains 0, resulting in 0.
5. What is the purpose of rounding off numbers to the nearest tens and hundreds place?
Ans. Rounding off numbers to the nearest tens and hundreds place helps in simplifying calculations and making estimations. It is particularly useful when dealing with large numbers or when you only need a general idea of the value. Rounding off can provide a quick approximation without the need for precise calculations, saving time and effort.
