How to round decimals to a required place value?
To round decimals to a required place value, follow these steps:

1. Identify the decimal place value you want to round to. For example, if you want to round to the nearest hundredth, you’re looking at the second decimal place (e.g., 0.12, 3.45).
2. Look at the digit immediately to the right of the decimal place value you want to round to. This is the “rounding digit”.
3. If the rounding digit is 4 or less, you round down. If the rounding digit is 5 or more, you round up.
4. If you’re rounding down, simply drop all the digits to the right of the decimal place value you’re rounding to. They become 0.
5. If you’re rounding up, increase the digit in the decimal place value you’re rounding to by 1, and drop all the digits to the right of it. If the digit you’re increasing is 9, it becomes 0 and you carry over the 1 to the next place value to the left.

Example:
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:
Decimal: 4.324
Rounding to the nearest tenths: 4.3
Decimal: 7.866
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
