Rounding Numbers Worksheet - Practice rounding to the nearest 10, 100, and 1,000 with "Round Up" or "Round Down" checkboxes.

To solve the problem of rounding the given numbers as specified, we need to follow the rules for rounding:

Rounding Rules:

1. Round to the nearest 10:
- Look at the digit in the ones place.
- If it is 5 or greater, round up.
- If it is less than 5, round down.

2. Round to the nearest 100:
- Look at the digit in the tens place.
- If it is 5 or greater, round up.
- If it is less than 5, round down.

3. Round to the nearest 1,000:
- Look at the digit in the hundreds place.
- If it is 5 or greater, round up.
- If it is less than 5, round down.

Now, let's solve each section step by step.

1. Round off to the nearest 10:

| Number | Rounded Value | Round Up | Round Down |
|--------|---------------|----------|------------|
| 154 | 150 | | ✓ |
| 3,739 | 3,740 | ✓ | |
| 4,502 | 4,500 | | ✓ |
| 67,117 | 67,120 | ✓ | |

- 154: The ones digit is 4 (less than 5), so round down to 150.
- 3,739: The ones digit is 9 (greater than 5), so round up to 3,740.
- 4,502: The ones digit is 2 (less than 5), so round down to 4,500.
- 67,117: The ones digit is 7 (greater than 5), so round up to 67,120.

2. Round off to the nearest 100:

| Number | Rounded Value | Round Up | Round Down |
|--------|---------------|----------|------------|
| 6,138 | 6,100 | | ✓ |
| 38,279 | 38,300 | ✓ | |
| 421,723 | 421,700 | | ✓ |
| 589,093 | 589,100 | ✓ | |

- 6,138: The tens digit is 3 (less than 5), so round down to 6,100.
- 38,279: The tens digit is 7 (greater than 5), so round up to 38,300.
- 421,723: The tens digit is 2 (less than 5), so round down to 421,700.
- 589,093: The tens digit is 9 (greater than 5), so round up to 589,100.

3. Round off to the nearest 1,000:

| Number | Rounded Value | Round Up | Round Down |
|--------|---------------|----------|------------|
| 7,725 | 8,000 | ✓ | |
| 2,943 | 3,000 | ✓ | |
| 68,481 | 68,000 | | ✓ |
| 84,473 | 84,000 | | ✓ |

- 7,725: The hundreds digit is 7 (greater than 5), so round up to 8,000.
- 2,943: The hundreds digit is 9 (greater than 5), so round up to 3,000.
- 68,481: The hundreds digit is 4 (less than 5), so round down to 68,000.
- 84,473: The hundreds digit is 4 (less than 5), so round down to 84,000.
