Answer: 24.3
Explanation:
To find the percentage of a number, simply multiply the whole by the percentage. 27% = 0.27, so 90×0.27 = 24.3
To round to the nearest tenth, look at the hundredths place. If the digit in the hundredths place is 4 or less, leave the digit in the tenths place (3) as it is. If it's 5 or greater, raise the number in the tenths place by 1.
In this case, the digit in the hundredths place is an "invisible 0." You may not be able to see it, but the 0 is always there, it just has no value and is sort of like a "placeholder."
Since 0 is less than 4, leave the number as 24.3.
