Question

On a multiple-choice test of

92 questions, a student gets 16 questions wrong. To the nearest tenth of a percent, what percent of the questions did the student solve correctly?

Answer 1

Answer: 82.6 %

Step-by-step explanation:
For this problem, we simply need to create an expression that represents the percentage the student solved correctly. We are given the information of what the student solved incorrectly (wrong). From this, we can assume a perfect score would be 100% which is represented by the whole number 1. Let’s build and simplify the expression below to find the percentage correct.

1 - (16 / 92)
= 1 - .174
= 0.826

Now to convert this value to a percent, we simply multiply by 100 to get 82.6%.

Cheers.
