1.05 Round numbers
Are you ready?
Can you round 3 or 4 digit numbers ?
Examples
Example 1
Round 7521 to the nearest thousand.
When rounding a number to the nearest thousands:
Use a number line to check if it is closer to the thousands above, or the thousands below the number.
If a number is exactly in the middle, round to the higher number.
Round numbers up to 5 digits
Sometimes we only need an approximation of our number, rather than the exact value. We work out which number it is closest to, and we can do this on a number line, or using the rule for rounding. Let's see how to do both of these things in this video.
Examples
Example 2
Round 96\,501 to the nearest thousand.
It doesn't matter how many places our numbers have, when we round the number, we need to know what we are rounding it to. If we round 130 to the nearest hundred, we will get a different answer than if we round it to the nearest ten.
