80% of 81 is 64.8. If you can get partial credit on questions, as some teachers and professors give, you must get at least 4/5 of the possible points on a 65th question, basically. Short of that, you need to answer 65 of the questions correctly, so you can only miss 16.

Use an equality. 65 questions/100% = Xquestions/86% 100X = 5590 X = 55.9 -------------------------call it 60 You missed 5 questions, or a partial question somewhere.
If you missed out 11 AND got all the rest correct you would have 83.08%. However, if you miss out 11 out of 65 it is unlikely that you are good enough to get all the rest correct!
To calculate the number of correct answers you got on a test, you can use the formula: (score / total possible score) x total number of questions. In this case, you got a score of 78 on a 65-question test. So, (78 / 100) x 65 = 50.7. Therefore, you got approximately 51 questions correct on the test.
To score 65% you would need to answer 32.5 questions correctly. As you can't answer half a question correctly, you will need to answer 33 correctly resulting in a mark of 66%. Thus you can miss 17.

If every question is worth the same credit, then 26 correct out of 40 is a score of 65 percent. The letter-grade is whatever the teacher decides 65% on that test is. I'm afraid there aren't many situations where 65% gets a passing grade.

She "missed" (erroneously answered) 16.92 % of the answers (11/65). She correctly answered 83.08 % of the answers (54/65). === === To get the answer, divide 11 by 65, which will give you .1692, which is equal to 16.92 percent. Round up to 17%, which means she made a score of 83 on the test.

If all the questions were worth the same amount and 100 percent was a perfect score, then each question would be worth five points and getting seven wrong would get you a 65. Since you got a 64, there must be some scoring information that you neglected to tell us.
If you missed out 11 AND got all the rest correct you would have 83.08%. However, if you miss out 11 out of 65 it is unlikely that you are good enough to get all the rest correct!
