How it works

Find the place. The digit next door decides.

If the next digit is 5 or more, round up. If it is less than 5, stay.

Everything after the place becomes zeros.

Look next door• the hundreds digit is 4• 4 is less than 5So• stay at 6000• the rest become zeros

Example 1: To the nearest thousand

  1. 6488 to the nearest thousand ?
  2. 6488: the hundreds digit is 4.
  3. 4 is less than 5, so stay at 6000.
  4. So the answer is 6000.

Example 2: To the nearest hundred thousand

  1. 132569 to the nearest hundred thousand ?
  2. 132569: the ten thousands digit is 3.
  3. 3 is less than 5, so 100000.
  4. So the answer is 100000.

Example 3: A carry

  1. 99999 to the nearest ten ?
  2. 99999 to the nearest ten: the ones digit is 9.
  3. Round up, and it carries to 100000.
