Answer 1

The correct option is A The round off digit is the place value of the number you're rounding to.

The round off digit is the place value of the number you're rounding to.

• If you want to round a number to the nearest ten, the round off digit is the number in the tens place. If you want to round a number to the nearest hundred, the round off digit is the number in the hundreds place.
• Example: Round off $456$ to the nearest tens place. Here, the digit at tens place is $5$, which needs to be rounded off. The number after rounding off 456 to the nearest tens place will be $460$.
