- 9 is in the tenths place and 8 is in the hundredths place
- Since the digit in the hundredths place (8) 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 (2)
- 1 + 2 = 3, so the digit in the ones place becomes 3
- The digits to the right of the tenths place are dropped
- 12.987 rounded to the nearest tenth (one decimal place) = 13.0
