Round to the Nearest Ten

Round to the Nearest Ten

Rounding to the nearest ten means replacing a whole number with the closest multiple of 10: 0, 10, 20, 30, and so on.

1) Find the tens and ones

Look at the digit in the ones place. The tens digit tells you the nearby ten below the number, and the next ten above is the following multiple of 10.

2) Decide which ten is closer

• If the ones digit is 0, 1, 2, 3, or 4, round down to the lower ten.
• If the ones digit is 5, 6, 7, 8, or 9, round up to the next ten.

3) Write the rounded number

Keep the tens digit and change the ones digit to 0.

Example

• 34 → 30
• 67 → 70
• 50 → 50

Check your answer

Ask: Is the rounded number a multiple of 10, and is it close to the original number? The answer should be the nearest ten, not just any ten.
