4 out of 10 is 40 percent
One-tenth of 40 is one-tenth times 40.40 x 1/10 = 40 ÷ 10 = 44
87.5%.
If you answered 23 correct out of 40 questions, your percent correct is 57.5%
If there are 20 questions then each question is worth 5 points because 100 total points divided by 20 equals 5.If you missed 8 questions then 8 times 5 points equals 40 points wrong, so you have to subtract that from 100 to get a grade of 60. Study harder next time.
40 minus 28 = 12 were wrong
40% were wrong.
10/40 wrong means 30/40 correct 30/40 = 75% correct

what is your grade percentage if you miss 6 questions out of 40
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.
If five people answer eight questions each, then there are 40 total questions. 5 x 8 = 40 If 12 of those 40 answers are wrong, then 30% of the questions are wrong. This leaves 70% of the questions to be right. 12 / 40 = 0.3 0.3 = 30% 40 - 12 = 28 28 / 40 = 0.7 0.7 = 70%
40% of 10 = 4 So four questions out of ten is answered correctly.
8 wrong i.e. 32 right 10% of 40 is 4 80% = 8 x 4 = 32 40 - 32 = 8
Each question is worth 2.5 percent. You can get 8 wrong.
68% D+
10 can be wrong and 30 right; 30/40 = 75%
