Ah, what a happy little question! When we round 401.92 to the nearest tenth, we look at the digit in the hundredths place, which is 2. Since 2 is less than 5, we keep the tenths place as it is, so 401.92 rounded to the nearest tenth is 401.9. Just a little adjustment, and now it's a perfect rounded number for you!
