27 * 81/100 = 22 problems correct -> 5 problems incorrect.
You might not have missed any - you just got nearly half of them wrong.
I took a test that had 35 questions. I got a 91%, how many did I miss?
25%
You multiply .78 times the amount of questions on the test (65). Which works out to 50.7, so either your teacher rounded or you got partial credit on a problem/ problems.
10% so you got a 90% on the test
7/60 = 0.11(6), so 7 is about 12% of 60. You would have an 88% on that test.
You can't get 90% in a test with 32 questions. However, if calculated the answer would be 3.2. i.e., you would miss 3.2 questions to get 90%. This can happen when the examiner gives you marks even for a partially correct answer.
If every question was worth the same credit, you missed 18 of them.
well i got 6 wrong out of 30 and i failed so im guessig its 6
83. You may have typed the question wrong.
0.70 x 125 = 88 questions right You can miss 125-88 = 37 questions to get 70 percent But you got to get all the rest correct!
My guess is that it wasn't a maths test. 32 X 0.82=26.24 so you missed 6. Your teacher gave you an extra mark as that comes to 81%.
