22.3

The answer will be 22.27105745...

To round to 1 decimal place:

1. Find the number on the first decimal place (the 3rd 2 in this case)

2. Look at the number on the right of it (7 in this case)

3. If the number on the right is 5 or greater round the number on the first decimal place up one value. If it is less than five keep it the same. In this situation the number 7 is greater than 5, so we round the 2 up to 3.
