For this case, the first thing to do is find the number of incorrect questions.
We have then:
[tex]60-43 = 17[/tex]
Then, we look for the wrong percentage of questions.
For them we divide by the total number of questions and multiply by one hundred.
[tex]\frac {17} {60} * 100 = 28.3 \%[/tex]
Answer:
the percentage to one decimal place is:
28.3 %
