If there are 85 questions, a passing grade of 80% would be 68 correct answers.
90% of 27 = 27*90/100 = 24.3 So you MUST answer 25 questions - ie all but 2 - AND get them all correct!
To achieve a score of 70 percent on a 50-question test, a student must answer at least 35 questions correctly (70% of 50). This means they can get a maximum of 15 questions wrong (50 - 35 = 15) and still meet the passing criteria.
100 - 69 = 31, and it's percent, so it's .31 .31*30 = 9.3, but you must round down or up (down to get more than 69%), so you can miss 9 questions and still fail.
50 gallons @ 3% must be added.
9.7% because you must move the decimal to places to the right. NEVER say it's 97%!
You would need to answer 68 questions correctly.
We must answer 3 questions.
28
60 percent = 60/100 60% of 40 = 60/100 x 40 = 24. Ans: 24 questions.
Each question is worth 2.5% so lets say the fail is 60%, you have to get 24 questions right to get a 60%, for an A you have to get 36 questions right.
You can miss out 12 but: you must get all the remaining correct and there must be no penalties for wrong answers.
35 out of 40.
30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%
-a 6/8 is a 75% -a 7/8 is an 87% So in order to get at least an 80%, you must score at least a 7
Oh, dude, you're really stressing about this, huh? Well, technically, if you want a 70 percent on a 70-question test, you can get 21 questions wrong. But like, who's counting, right? Just do your best and hope for a generous curve!
Because you must ask the right questions =)
