- 9 is in the hundredths place and 9 is in the thousandths place
- Since the digit in the thousandths place (9) is greater than or equal to 5, add 1 to the digit in the hundredths place (9)
- 1 + 9 = 10, so the digit in the hundredths place becomes 0, and 1 is added to the digit in the tenths place (0)
- 1 + 0 = 1, so the digit in the tenths place becomes 1
- The digit in the thousandths place is dropped
- 0.099 rounded to the nearest hundredth (two decimal places) = 0.10
