Worked Examples

Worked Example 1

One Number, Three Ways

Round 4,682 to the nearest 10, 100, and 1,000.
  1. 1Nearest 10: the ones digit is 2, so round down to 4,680.
  2. 2Nearest 100: the tens digit is 8, so round up to 4,700.
  3. 3Nearest 1,000: the hundreds digit is 6, so round up to 5,000.
Answer: 4,680; 4,700; 5,000

Worked Example 2

Rounding Up Past a 9

Round 7,950 to the nearest 100.
  1. 17,950 is between 7,900 and 8,000.
  2. 2The tens digit is 5, so round up.
  3. 3One more hundred than 7,900 is 8,000.
Answer: 8,000

Common Mistakes to Watch For

Rounding in steps

Wrong:3,449 → 3,450 → 3,500 → 4,000 (nearest 1,000)

Round in one step. For the nearest 1,000, look at the hundreds digit: 4, so 3,449 rounds to 3,000.

Not carrying into the next place

Wrong:9,962 rounded to the nearest 100 is 9,900.

9,962 is between 9,900 and 10,000, and it is closer to 10,000.

Helpful Math Tip

Underline the place you're rounding to and circle the digit to its right. The circled digit decides up or down.
