Dillon answered 80% of the questions on a quiz correctly. If he answered 40 questions correctly, what was the total number of questions on Dillon's quiz?

If he answered 80% correct turn that into a fraction and you get 80/100. Since 80 divided by 2 equals 40, divide 100 by 2. So you get 40/50. He got 40 questions right out of a total of 50

50 is correct ... so, yeah ...
