Question

Marissa got a 75% on her quiz. She had 30 questions correct. How many questions were on the quiz?

Answer 1

questions * 75 percent = 30 correct

question * .75 = 30

divide by .75 on each side

questions = 30/.75

questions = 40

There were 40 questions

Answer 2

40

Think of it this way

If it is 75% and there is 30.

75 divided by 3 = 25

So 10 questions is 25%

75 + 25 = 100

So 30 + 10 = 40
