- 9 is in the tenths place and 9 is in the hundredths place
- Since the digit in the hundredths place (9) is greater than or equal to 5, add 1 to the digit in the tenths place (9)
- 1 + 9 = 10, so the digit in the tenths place becomes 0, and 1 is added to the digit in the ones place (9)
- 1 + 9 = 10, so the digit in the ones place becomes 0, and 1 is added to the digit in the tens place (9)
- 1 + 9 = 10, so the digit in the tens place becomes 0, and 1 is added to the digit in the hundreds place (9)
- 1 + 9 = 10, so the digit in the hundreds place becomes 0, and 1 is added to the digit in the thousands place (0)
- 1 + 0 = 1, so the digit in the thousands place becomes 1
- The digit in the hundredths place is dropped
- 999.99 rounded to the nearest tenth (one decimal place) = 1,000.0
