73%.
To find out your grade, divide 100 by however many questions there are (in this case 26). Multiply the number you get by how many you got wrong (7). Then subtract the number you got from multiplying from 100. This is your score.
3 ouf of 20 questions wrong
If the teacher is not using a curve, 33-7=26 so there are 26 questions right. The percent correct is 26/33 or 78.78787878 percent with the 78 in the decimal recurring, meaning this is a 78.8 or a 79, which is a C or a C+ in many grading systems.
71 percent
When I graded papers, no matter how many questions, I would mark the questions wrong that were wrong with checks. Then, to come up with a grade I would subtract the number possible with the number wrong. That would give me the total number right and from that you assign a grade to the paper.
10 - 3 = 7 7 / 10 = .7 = 70%
7 wrong out of 22 questions = 31.8% wrong. 15 correct out of 22 questions = 68.2% correct. I hope it wasn't a math test.
70% , which is a C. If you got 6 wrong, that means you got 14 right. 14/20 can simplify down to 7/10 (divide both the numerator and denominator by 7), and 7/10 is a 70%.
65% or D
You are in the C-D range. If you had missed 7 out of 15 that would be a solid D. You can do better I don't know you but I know you can do better.
no more than 7
70% of 25 is 17.5. That is you will pass with 7 (7.5) questions wrong.
Even if you assume the questions are all worth the same number of marks, the answer may well depend on the grade boundaries.
Grade 7 is the rating on which your insurance is based on. The lower the number the lower the car insurance. For Example my car is a grade 26 which is one of the highest grades you can get grade 7 will be fairly cheap.
