Answer:

• 468 can be rounded off to the number 470.
• 222 can be rounded off to the number 220.

Step-by-step explanation:

Rounding Rules for Whole Numbers are as follows:

• Always choose the smaller place value to get an accurate final result.

• Find out the next smaller place that is towards the right of the number which is being rounded off. For example, if we have to round off a digit from the tens place, we have to look for a digit in the one’s place.
• If the digit in the smallest place is less than 5,  the digit will be left untouched. Any number of digits after that number will become zero. This is known as rounding down.
• If the digit in the smallest place is greater than or equal to 5, then the digit will be added with (+1). Any digits after that number will become zero and this procedure is known as rounding up.

455, 468,442,491 are the given numbers. we have to find out which number can be rounded off to the number 470.

• Using rounding up rule , we can say that 468 can be rounded off to the number 470.

222,228,292,238 are the given numbers. we have to find out which number can be rounded off to the number 220.

• Using rounding down rule , we can say that 222 can be rounded off to the number 220.
