How many questions can be wrong on a 55 questions test to get 80 percent?

To achieve an 80% score on a 55-question test, you would need to answer 44 questions correctly (55 questions x 0.80 = 44 questions). To find out how many questions you can get wrong, subtract the number of correct answers from the total number of questions: 55 total questions - 44 correct answers = 11 questions wrong. Therefore, you can get 11 questions wrong on a 55-question test and still achieve an 80% score.
