Rounding a number to the nearest ten means finding the multiple of ten that the number is closest to. If the digit in the ones place is 5 or greater, the number is rounded up; otherwise, it is rounded down. For example, rounding 195 to the nearest ten gives 200, and rounding 860 to the nearest ten gives 860 itself
. This process can be summarized by the following steps:
- Identify the digit in the tens place.
- Look at the digit in the ones place.
- If the digit in the ones place is 5 or greater, round up; otherwise, round down.
For instance, rounding 38 to the nearest ten involves identifying the tens place (3), looking at the ones place (8), and then rounding up to 40 because 8 is greater than 5
. Similarly, rounding 105 to the nearest ten results in 110, as the digit in the ones place (5) is rounded up to 0, and the digit in the tens place (0) is increased by 1
