Math worksheet for rounding numbers to the nearest 100.

To solve the problem of rounding numbers to the nearest 100, we need to follow these steps:

Steps for Rounding to the Nearest 100:

1. Identify the tens digit: Look at the digit in the tens place of the number.
2. Decide whether to round up or down:
- If the tens digit is 5 or greater, round up by increasing the hundreds digit by 1.
- If the tens digit is less than 5, round down by keeping the hundreds digit the same.
3. Set all digits to the right of the hundreds place to zero.

Example:

- For the number 6386:
- The tens digit is 8 (which is ≥ 5).
- Round up: Increase the hundreds digit (3) by 1 → 4.
- Result: 6400.

Now, let's apply this method to all the numbers in the table.

Solving Each Number:

#### Row 1:
- 6386: Tens digit = 8 (≥ 5) → Round up → 6400.
- 7456: Tens digit = 5 (≥ 5) → Round up → 7500.
- 2489: Tens digit = 8 (≥ 5) → Round up → 2500.

#### Row 2:
- 7738: Tens digit = 3 (< 5) → Round down → 7700.
- 5431: Tens digit = 3 (< 5) → Round down → 5400.
- 2587: Tens digit = 8 (≥ 5) → Round up → 2600.

#### Row 3:
- 2349: Tens digit = 4 (< 5) → Round down → 2300.
- 3458: Tens digit = 5 (≥ 5) → Round up → 3500.
- 4567: Tens digit = 6 (≥ 5) → Round up → 4600.

#### Row 4:
- 5641: Tens digit = 4 (< 5) → Round down → 5600.
- 3428: Tens digit = 2 (< 5) → Round down → 3400.
- 5632: Tens digit = 3 (< 5) → Round down → 5600.

#### Row 5:
- 8180: Tens digit = 8 (≥ 5) → Round up → 8200.
- 9142: Tens digit = 4 (< 5) → Round down → 9100.
- 1258: Tens digit = 5 (≥ 5) → Round up → 1300.

#### Row 6:
- 4326: Tens digit = 2 (< 5) → Round down → 4300.
- 4350: Tens digit = 5 (≥ 5) → Round up → 4400.
- 6153: Tens digit = 5 (≥ 5) → Round up → 6200.

#### Row 7:
- 4327: Tens digit = 2 (< 5) → Round down → 4300.
- 6452: Tens digit = 5 (≥ 5) → Round up → 6500.
- 4125: Tens digit = 2 (< 5) → Round down → 4100.

#### Row 8:
- 1349: Tens digit = 4 (< 5) → Round down → 1300.
- 9261: Tens digit = 6 (≥ 5) → Round up → 9300.
- 2274: Tens digit = 7 (≥ 5) → Round up → 2300.
