Answer:
7.987, 8.4082, 8.48, 8.8
Explanation:
7 is less than 8 (7 < 8) so it would be first. The first place after the decimal, also known as the tenths place decides the numbers that come after. 8.4082 and 8.48 seem similar but are pretty different. When you round 8.4082 it becomes 8.41 which is less than 8.48. That leaves just 8.8 which is your highest number.
