### Rounding Whole Numbers Worksheets

Rounding whole numbers needs the understanding of the decimal places. (You can review our previous post which talked about decimal places.) To round to the nearest decimal place means to find the closest number having all zeros to the right of the that decimal place. Our rule of rounding numbers states that when the digit 5, 6, 7, 8, or 9 appears in the lower one decimal place, round up; when the digit 0, 1, 2, 3, or 4 appears in the lower one decimal place, round down.

Specifically, to round to the nearest thousands place means to find the closest number having all zeros to the right of thousands place. Hence, when the digit 5, 6, 7, 8, or 9 appears in the hundreds place, round up; when the digit 0, 1, 2, 3, or 4 appears in the hundreds place, round down.

Examples: Round each to the place indicated.

1. Rounding 127 to the nearest ten gives 130.
2. Rounding 2085 to the nearest ten gives 2090.
3. Rounding 4303 to the nearest ten gives 4300.
4. Rounding 180 to the nearest hundred gives 200.
5. Rounding 130,180 to the nearest hundred thousand gives 100,000.
6. Rounding 1343 to the nearest thousand gives 1000.
7. Rounding 145,652,003 to the nearest million gives 146,000,000.
8. Rounding 1455 to the nearest hundred gives 1,500.
9. Rounding 101 to the nearest hundred gives 100.
10. Rounding 101,111,119 to the nearest ten gives 101,111,120.
