How to round decimals to a required place value?
To round decimals to a required place value, follow these steps:
Let’s say you want to round the number 3.287 to the nearest hundredth. The hundredth place value is the second decimal place, which is 8. The rounding digit is 7 (the digit immediately to the right of the hundredth place value). Since 7 is greater than 5, you round up. Increase the hundredth place value by one: 3.29 (rounded up from 3.287).
Here are some additional examples:
Rounding to the nearest tenths: 4.3
Rounding to the nearest hundredths: 7.87
In general, we can use this rhyme to help us remember what to do:
Find the place and look right next door
5 or higher, add one more
4 or less, just ignore
