Round 2-digit numbers to the nearest 10

Rounding 2-digit numbers to the nearest 10 means finding the multiple of 10 that is closest to the given number. Here’s how you can round a 2-digit number to the nearest 10, along with an example:

  1. Identify the 2-digit number you want to round.
  2. Look at the digit in the units (ones) place. If this digit is 0 to 4, you round down to the nearest 10. If it’s 5 to 9, you round up to the nearest 10.
  3. Replace the digit in the units place with 0 and keep the tens place unchanged if you’re rounding down. If you’re rounding up, increase the tens place by 1 and replace the units place with 0.

Here’s an example:

Let’s say you want to round the number 36 to the nearest 10.

  1. You have the 2-digit number 36.
  2. The digit in the units place is 6, which is greater than 4, so you will round up.
  3. Increase the tens place by 1 (3 + 1 = 4) and replace the units place with 0.

So, when you round 36 to the nearest 10, you get 40.

Here are a few more examples:

  • Rounding 45 to the nearest 10: The units digit is 5 (greater than or equal to 5), so you round up. Increase the tens place by 1, and replace the units place with 0. Result: 50.
  • Rounding 29 to the nearest 10: The units digit is 9 (greater than or equal to 5), so you round up. Increase the tens place by 1, and replace the units place with 0. Result: 30.
  • Rounding 73 to the nearest 10: The units digit is 3 (less than 5), so you round down. Keep the tens place unchanged and replace the units place with 0. Result: 70.
