To calculate your score, first, determine how many questions you answered correctly. If you got 9 wrong out of 40 questions, that means you answered 31 questions correctly (40 - 9 = 31). To find the percentage score, divide the number of correct answers by the total number of questions and multiply by 100: (31/40) × 100 = 77.5%. Therefore, your score is 77.5%.
40 minus 28 = 12 were wrong
10/40 wrong means 30/40 correct 30/40 = 75% correct
If there are forty and you got twelve wrong, then you got twenty-eight correct. 28 out of 40 = 70%
70% or C-
40 over 45 is 88%
A test score of "90" represents the percentage of correct questions. Multiply this percentage by the total number of questions and you will have the number of questions correctly answered. Subtract this from the total to find answers wrong. 90% of 40 questions = .90 x 40 = 36 questions right. 40-36 = 4 answers wrong.
40 minus 28 = 12 were wrong
10/40 wrong means 30/40 correct 30/40 = 75% correct
If there are forty and you got twelve wrong, then you got twenty-eight correct. 28 out of 40 = 70%

If you got 14 out 25 questions right you should get a 40. This is a low grade.
40 over 45 is 88%
To achieve 80 percent on a 40-question test, you need to answer at least 32 questions correctly (80% of 40 is 32). This means you can only get 8 questions wrong (40 - 32 = 8). Therefore, to score 80 percent, you can afford to miss a maximum of 8 questions.
Ans: 30%. Working: 40-28=12 12/40 x100%=30%
40% were wrong.
35%
If by grade you mean percentage, you would have scored 67.5%. 40-13= 27 (27/40) * 100
