Understanding Percentages in Test Scores

The video tutorial explains how to determine the percentage of questions Brooke missed on a multiple-choice English vocabulary test. Brooke answered 29 out of 35 questions correctly, meaning she missed 6 questions. The tutorial demonstrates two methods to find the percentage of missed questions: converting the fraction of missed questions to a percentage and using a percent equation. Both methods yield the same result, showing that Brooke missed 17.1% of the questions.
