- 9 is in the ones place and 9 is in the tenths place
- Since the digit in the tenths place (9) 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 (9)
- 1 + 9 = 10, so the digit in the tens place becomes 0, and 1 is added to the digit in the hundreds place (9)
- 1 + 9 = 10, so the digit in the hundreds place becomes 0, and 1 is added to the digit in the thousands place (6)
- 1 + 6 = 7, so the digit in the thousands place becomes 7
- The decimal point and the digit in the tenths place are dropped
- 36,999.9 rounded to the nearest whole number (ones place) = 37,000
