15 sudents completed 80 puzzels how many puzzles would 1 sudent complete round to the nearest tenth

To find out how many puzzles one student would complete, you can divide the total number of puzzles by the total number of students:

\[ \text{Puzzles per student} = \frac{\text{Total puzzles}}{\text{Total students}} = \frac{80}{15} \]

Calculating that gives:

\[ \frac{80}{15} \approx 5.3333 \]

Rounding to the nearest tenth, this would be approximately \(5.3\).

Thus, one student would complete approximately 5.3 puzzles.
