- 1 is in the ones place and 5 is in the tenths place
- Since the digit in the tenths place (5) is greater than or equal to 5, add 1 to the digit in the ones place (1)
- 1 + 1 = 2, so the digit in the ones place becomes 2
- The decimal point and the digits to the right of the ones place are dropped
- 21.532 rounded to the nearest whole number (ones place) = 22
