Rounding numbers to the nearest hundred:

is finding the closest multiple of 100 to a given number. When rounding to the nearest hundred, we focus on the tens digit to determine whether to round up or down.

How to round to the nearest hundred:

1. Identify the ten digit of the number.
2. If the tens digit is 5 or more, round up by increasing the hundreds digit by 1, and changing the tens and ones digits to 0.
3. If the tens digit is less than 5, round down by keeping the hundreds digit the same and changing the tens and one's digits to 0.

Example 1:

Rounding 347 to the nearest hundred:

• • Look at the tens digit: 4.
  • Since 4 is less than 5, round down.
  • 347 becomes 300.

• Example#02

  Rounding 684 to the nearest hundred:

  • Look at the tens digit: 8.
  • Since 8 is 5 or more, round up.
  • 684 becomes 700.

• Example#03:

  Round 849 to the nearest 100:

  • Step 1: Look at the tens place. In 849, the tens digit is 4.
  • Step 2: Since the tens digit is less than 5, round down.
  • 849 rounded to the nearest 100 is 800.

• Example#04:

  Round 965 to the nearest 100:

  • Step 1: Look at the tens place. In 965, the tens digit is 6.
  • Step 2: Since the tens digit is 5 or more, round up.
  • 965 rounded to the nearest 100 is 1000.

• Example#05:

  Round 110 to the nearest 100:

  • Step 1: Look at the tens place. In 110, the tens digit is 1.
  • Step 2: Since the tens digit is less than 5, round down.
  •  110 rounded to the nearest 100 is 100.
