Question

What is the ratio of students scoring above 80 to students scoring exactly 80 on this test

Answer 1

19 to 1

Explanation:

The number of students who scored above 80

`\begin{gathered} =9+18+72+15 \\ =114 \end{gathered}`

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:

`\begin{gathered} 114:6 \\ \text{ Divide both sides by 6} \\ =(114)/(6):(6)/(6) \\ =19:1 \end{gathered}`

The ratio is 19 to 1.

The last option is correct.
