15. Students completed 80 puzzles how many puzzles would one student complete round the answer to the nearest tent is the answer 5.3 1.6,15.0 or 0.2.
To find out how many puzzles one student would complete, we can divide the total number of puzzles completed (80) by the number of students. However, the number of students is not provided in the question. Therefore, we cannot determine the exact number of puzzles one student would complete.
If we round the answer to the nearest tenth, the options are 5.3, 1.6, 15.0, or 0.2. However, none of these options is a reasonable approximation since we cannot accurately determine the number of puzzles one student would complete without knowing the number of students.
