When rounding 21.9 to the nearest tenth, you look at the digit in the hundredths place, which is 9. Since 9 is equal to or greater than 5, you round up the digit in the tenths place by 1. Therefore, 21.9 rounded to the nearest tenth is 22.

Well, honey, 21.9 rounded to the nearest tenth is 22.0. It's as simple as that. No need to make a big fuss over it. Just round up and move on with your day.
