Fifteen students completed 80 pizzles. How many puzzles would 1 student complete? Round the answer to the nearest tenth.

A. 1.6
B. 5.3
C. 15.0
D. 0.2

To find out how many puzzles 1 student would complete, we need to divide the total number of puzzles by the number of students. In this case, 80 puzzles were completed by 15 students.

Now we calculate:

80 puzzles / 15 students = 5.3333...

Rounded to the nearest tenth, this would be 5.3 puzzles per student.

Thus, the correct answer is:

B. 5.3
