- 9 is in the hundredths place and 8 is in the thousandths place
- Since the digit in the thousandths place (8) 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 (7)
- 1 + 7 = 8, so the digit in the tenths place becomes 8
- The digit to the right of the hundredths place is dropped
- 2.79890806 rounded to the nearest hundredth (two decimal places) = 2.80
