Question

Dalvin answered 51 questions correctly on his multiple choice science final and earned a grade of 85%. How many total questions were on the final exam?

Answer 1

60

Explanation:

Divide the number of questions answered correctly by his percentage

51 / 85 = 0.6

Now multiply that answer by 100 to see how many questions are on the quiz

0.6 x 100 = 60

Check your work by dividing that number by the number he answered correctly

51 / 60 = 0.85
