Answer:
22.4
Explanation:
In 22.384, the 4 at the end does not matter. In order to round it to the nearest tenth, you only need the number right after the number in the tenths place. So for this problem, you'd look at the number in the hundredths place (22.384): if the number after the one you're rounding is equal to or higher than 5, you round it up. If it's less than 5, you round it down. So since 8 is bigger than 5, you would round the 3 in the tenths place up to 4 to make the number 22.4.
