Answer:

You missed 5 questions.

Explanation:

If you multiply 25 by 4 to get one hundred, the total amount of points, you can find that your 80 out of 100 is your 80%.

I'm assuming that each question is 4 points each because you have to multiply the 25 questions by 4.

100-80 is the percent that you missed.

100-80=20

20÷4=5

You missed 5 questions.
