Rounding Numbers: Learn

How to round numbers

  • Make the numbers that end in 1 through 49 into the next lower number that ends in 00. For example 424 rounded to the nearest hundred would be 400.
  • Numbers that have the last two digits of 50 or more should be rounded up to the next even hundred. The number 988 rounded to the nearest hundred would be 1000.
