How
to Round Whole Numbers
Step 1: Choose the place value that you want to
round a number to - meaning the 10's, 100's, 1 000's or another
place value.
ie: Round 6 458 to
the nearest hundred
- In this case we are rounding to the hundred's place.
Step 2: Decide what two multiples the number you
are rounding is between.
ie: We are rounding to the hundred's place so we would choose
multiples of 100. So: 6 458
is between 6 400
and 6 500
Step 3: Look to the digit in the place immediately
right of the place you are rounding to and use the rounding rules
to decide whether you move it up to the higher multiple or round
to the lower multiple.
ie: Look in the ten place of the number 6 458.
We see a 5, so we must round to the higher number.
Therefore: Round 6
458 to the nearest hundred = 6 500 |
