- 2 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 (2)
- 1 + 2 = 3, so the digit in the tenths place becomes 3
- The digits to the right of the tenths place are dropped
- 31.297 rounded to the nearest tenth (one decimal place) = 31.3
