Tips to Round a Number to the Nearest 100

Before going into our worksheets, let’s look at the following tips for rounding a number to the nearest 100. Understand these tips carefully, as they will be needed to solve all the problems given in the later discussion.

  • Take a number, whether it is a two-digit or a three-digit one.
  • See the digits of the Tens place of that number.
  • If the digit in the Tens place is less than 5, then to round that specific number you have to change the digit in the Tens place and Ones place to 0.
  • For example, look at the number 825. Here, the digit in the Tens place is 2, which is less than 5. So, to round this number, we will change both the numbers of Tens place and Ones place to 0. After rounding, 825 will become 800.
  • Now, if the number in the Tens place is equal to 5 or more than 5, then you not only have to change the Tens and Ones place’s digit to 0 but also have to add 1 with the digit in the Hundreds place.
  • For example, take the number 675. As the digit of Tens place is 7, which is more than 5, adding 1 to the Hundreds place and changing the later digits into 0, we get 700 after rounding up 675 to its nearest 100.
