- 9 is in the ones place and 8 is in the tenths place
- Since the digit in the tenths place (8) is greater than or equal to 5, add 1 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 (2)
- 1 + 2 = 3, so the digit in the tens place becomes 3
- The decimal point and the digit in the tenths place are dropped
- 29.8 rounded to the nearest whole number (ones place) = 30
