If you think there is one universal pass percentage for the worlds education system... look less to A and more to F
If you got 20 problems wrong on a 75 question test your grade would be 73% or a C. You can find that by subtracting the amount of questions you got wrong from the amount you got right, 55 in this case. Divide the amount of correct questions by the amount of questions on the test to get .733333. That is the grade.
Take the number of questions you got right and divide that by the total number of questions. Then times it by 100. ex. You got 10 questions right out of a 25 question test. 10/25= 0.40 x 100 = 40%. That's pretty bad!
Since there are only two options for the answer, on average the student will answer half of the answers correctly.
There are many ways, particularly in shopping. For example, if you buy x amount of hamburgers, and they cost c amout of money, and you have $20, you have to know if x decreases (you have to buy less hamburgers.) I have an Iowa standard pre-algebra test today so it's all fresh in my memory! That was kind of like a question we had. If you have anymore questions email me atrecycleordie@moose-mail.comThanks!
Cover the options and figure out which fits best.
If the TABE test has 90 questions, how many I can miss to pass the test?
You can miss 10% of questions, or 12 questions
There's like 46 questions. You can miss 7.
20
56.
54
24 of them.
22 questions
To get at least 90% on a 50 question test, you can miss no more than 5 questions.
