- 1 + 9 = 10, so the digit in the ones place becomes 0, and 1 is added to the digit in the tens place (4)
- 1 + 4 = 5, so the digit in the tens place becomes 5
- The decimal point and the digits to the right of the ones place are dropped
- 149.57 rounded to the nearest whole number (ones place) = 150
