The answer is the percentage receved to the total possible percentage, 80% = 80/100. You then simplify to the lowest possible answer giving yourself the ratio 4/5
Then the ratio of correct answers to incorrect answers would be :

80/20
=8/2
=4/1
The answer is 4:1 in simplified form.

I hope this helped you.
Have a wonderful day!
