15. Students completed 80 puzzles how puzzles with one student complete round answer to the nearest 10th
It is not possible to determine how many puzzles one student would complete in a round based on the given information.
To find out how many puzzles one student completes in a round, we need to divide the total number of puzzles completed by the students by the number of students.
Let's say there are "n" students.
If 80 puzzles were completed by all the students, and we want to find out how many puzzles one student completes in a round, we can use the following formula:
Number of puzzles completed by one student in a round = Total number of puzzles completed / Number of students
Let's substitute the known values into the formula:
Number of puzzles completed by one student in a round = 80 puzzles / n students
Since we are asked to round to the nearest 10th, we can express the answer using decimal places.
Therefore, the number of puzzles completed by one student in a round is approximately 80/n.
To find out how many puzzles one student can complete in a round, we need to divide the total number of puzzles completed by the number of students. In this case, 80 puzzles were completed by an unspecified number of students.
Without knowing how many students there are, it is not possible to determine how many puzzles each student completes in a round. Thus, we cannot accurately answer the question and provide a rounded answer to the nearest 10th.
