Question

On a multiple choice test of 86 questions, a student get 8 questions wrong. To the nearest percent, what percent of the questions did the student solve.

Answer 1

The answer is 91%

(the original decimal was 90.6976 so I rounded up to 91.)
basically if the student gets 8 questions wrong, this means he got 78 questions right. if we turn this into a fraction (78/86) and then multiply if by 100 we would get a percentage
