To round a decimal to the nearest tenth, look at the hundredth place. If the digit in the hundredth place is 5 or greater, round up. If the digit in the hundredth place is less than 5, round down.
In this case, the decimal is 221.574.
The digit in the hundredth place is 4, which is less than 5. Therefore, the decimal rounds down to the nearest tenth.
