Question

Sue answers 43 out of 60 questions correctly. What percentage of her answers are incorrect? Round the percentage to one decimal place.

Answer 1

For this case, the first thing to do is find the number of incorrect questions.

We have then:

$60-43 = 17$

Then, we look for the wrong percentage of questions.

For them we divide by the total number of questions and multiply by one hundred.

$\frac {17} {60} * 100 = 28.3 \%$

Answer:

the percentage to one decimal place is:

28.3 %
