In a question about rounding, the question will tell us which place value to round to. It may say ‘round to the nearest hundred’ or ‘round to the nearest thousand’
In order to round, we have to look at the digit to the right of the one we need to be rounding. So if we’re rounding to the nearest hundred, we have to look at the tens column.
If the number in that column is 4 or less , the number is rounded down.
If the number in that column is 5 or more, the number is rounded up.
We can also use this same method on decimal numbers.
Sometimes, if there is a question with complicated numbers in a calculation, you can use rounding to get a quick estimate of the answer
