When you round to the nearest tenth, you just look at the tenths place. In this case it's the 8. If the next number is below 5 then it stays the same. If it's above you add one. So your number would be 5,280. If the original number was 5,286 then the answer would be 5,290. Anyway the final answer is 5,280.
When rounding 5,282 to the nearest ten, you look at the ones place, which is 2. Since 2 is less than 5, you round down to 5,280. Therefore, the final answer is 5,280.
