A perfect score on a test with 25 questions is 100.
Each question is worth 4 points.
=> 25 * 4 points = 100 points.
Fred got a score of 80 on the tes.
We need to write a division sentence usingnegative numbers where the quotient represents the number of questions Fred answered incorrectly
=> 100 - 80 = 20 points.
=> 20 / 4 points = 5 questions
