Rounding Numbers to the Nearest Ten
Rounding numbers to the nearest ten involves looking at the digit in the ones place to determine whether to round up or down. If the digit in the ones place is 5 or greater, you round up. If it's less than 5, you round down.
When rounding a number like 438 to the nearest ten, we focus on the digit in the ones place, which is 8. Since 8 is greater than 5, we round up. This means the tens place digit will increase by 1. Therefore, 438 rounded to the nearest ten is 440.
The key point is to look at the digit in the ones place. If it's 5 or greater, we round up. If it's less than 5, we round down. In the case of 438, 8 is greater than 5, so we round up to 440.
