Question 978075: If a student gets an 95% on a 80-question test, how many did they answer correctly? Explain how did you find your answer. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 80 questions *95% correctly.
The answer is 80*0.95=76
Look at it this way
5% were incorrect.
What is 5% of 80?
Well, 10% is 8
so 5% is half 8 or 4.
There were 4 incorrect answers, so there must be 80-4=76 correct ones.
