Question 873942: The test is only 75 questions and you must get 90% or higher to continue on to the next course. Howmany can you get wrong??
I tried to divide 100 ÷ 75 = 1.3333333
Then multiple that 1.33333× 75
My answer was 1.
If this is correct that means you can only get one wrong.

You can put this solution on YOUR website!
90% of 75 = (90/100)*75 = 0.90*75 = 67.5


Round up to get 67.5 ---> 68


You must get at least 68 questions right to get a 90% or higher.


So you can miss up to 75 - 68 = 7 questions.
