Rounding Numbers
  • Rounding makes numbers that are easier to work with in your head.
  • Rounded numbers are only approximate.
  • An exact answer generally can not be obtained using rounded numbers.
  • Use rounding to get a answer that is close but that does not have to be exact.

    How to round numbers

  • Make the numbers that end in 1 through 4 into the next lower number that ends in 0. For example 74 rounded to the nearest ten would be 70.
  • Numbers that end in a digit of 5 or more should be rounded up to the next even ten. The number 88 rounded to the nearest ten would be 90.
