Ah, rounding numbers can be a peaceful journey. When we look at 720 and want to round it to the nearest ten, we see that the tens digit is 2. Since the next digit is 0, we leave the tens digit as it is, and the answer is 720. Just a little adjustment to keep things tidy and harmonious.

724 rounded to the nearest ten is 720. When rounding a number to the nearest ten, you look at the digit in the ones place. If it is 5 or greater, you round up; if it is less than 5, you round down. In this case, the digit in the ones place is 4, so we round down to the nearest ten, which is 720.

The answer will depend on the degree to which the number is rounded. Without any indication of that, it is not possible to answer the question sensibly.
To round 726 to the nearest ten, we look at the digit in the tens place, which is 2. Since 2 is less than 5, we keep the tens digit the same and change all digits to the right to zero. Therefore, rounding 726 to the nearest ten gives us 730.
