Identify Ones Digit: To round a number to the nearest ten, we look at the digit in the ones place. If it is 5 or greater, we round up. If it is less than 5, we round down. In the number 32.333567809, the digit in the ones place is 2, and the digit to its right is 3.
Check Next Digit: Since the digit to the right of the ones place (3) is less than 5, we do not round up. Therefore, we keep the digit in the tens place as it is and change all other digits to the right to zero.
Round to Nearest Ten: The number 32.333567809 rounded to the nearest ten is 30.
