53.1% or F
Well, honey, if you got 4 wrong out of 17 questions, you'd have 13 correct. So, you take your correct answers, divide by the total questions, multiply by 100, and voila, you've got yourself a grade. Math doesn't lie, darling.
a d-
You would get a 94% for a grade which is typically going to be an A.
If you have 20 questions and you get 3 wrong, that means you answered 17 questions correctly. Your score would be 17 out of 20. This can be expressed as a percentage by calculating (17/20) * 100, which equals 85%.
17/25 = 68%. In most American grading systems it would be a D, but it really depends. Sometimes a 68% could be a very good score, sometimes it is a very bad score.
88% or B+
I assume you mean the percentage of 17 out of 20. If not, then I apologize, I misunderstood. Anyway, if I assumed correctly then 17/20 is in fact 85%.
About a 66. Divide the number you got correct (in this case 34) by the total number of questions. (51)
85% or B
To calculate the grade, divide the number of correct answers by the total number of questions: (20 - 3 = 17) correct answers. Then, calculate the percentage: (\frac{17}{20} \times 100 = 85%). Therefore, getting 3 questions wrong out of 20 results in a grade of 85%.
if 17 then you should be in either 11th or 12th grade
