Answer:
19 to 1
Explanation:
The number of students who scored above 80
[tex]\begin{gathered} =9+18+72+15 \\ =114 \end{gathered}[/tex]
The number of students who scored exactly 80 = 6.
The ratio of students scoring above 80 to students scoring exactly 80 on this test is:
[tex]\begin{gathered} 114:6 \\ \text{ Divide both sides by 6} \\ =\frac{114}{6}:\frac{6}{6} \\ =19:1 \end{gathered}[/tex]
The ratio is 19 to 1.
The last option is correct.
