Question

If you get an 85% on a quiz and the quiz is 40 questions how many questions did you get right?

Answer 1

34

Explanation:

To do this we have to find the greater number, 100%=40 Questions. So then x=40, By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have.
`(40)/(x) =(100)/(85)`%

Again, the reciprocal of both sides gives
`(x)/(40) =(85)/(100)`. And x=34. So 85% of 40=34

Answer 2

Answer: 34 questions

Explanation:

If you have 40 questions, you have to find out what each question is worth which was 2.5 points per question. Then you divide 85 percent by 2.5 points and you get your answer that you got a total of 34 questions corrects to get an 85%.
