The number of win and losses of the volleyball team is related by a constant number, 3. This means that they're proportional. To find if the other teams also have proportional win-loss records we need to divide the number of their wins by the number of losses, if the result is an integer number, then they're proportional. We have:
[tex]\begin{gathered} \text{ basketball=}\frac{12}{5}=2.4 \\ \text{ football=}\frac{3}{1}=3 \\ \text{ wrestling=}\frac{12}{6}=2 \\ \text{ debate =}\frac{3}{4}=0.75 \end{gathered}[/tex]Since the football team has a proportional win-loss record with the same proportion as the Volleyball team, then this is the correct answer.
