Question

Annie's math test had 25 questions. She got 84% correct. How many problems did she get wrong?

Answer 1

She got 4 wrong because if you find how much is 84% of 25 by multiplying 84% times 0.25 you would get 21. In this case 21 is 84% of 25 and if you were to subtract 25 to 21 you would get 4. So she got 4 wrong
