Answer:
The correct answer is 28.1
Explanation:
When in a number we have to round up to 3 significant figures then we look at the 4 positions in the given number.
In 4th place, if the number is 5 or greater than 5 then we round up the number otherwise we round down the number.
Here the 4th place is the number 8 which is greater than 5 so we round it up and the number becomes 28.1
