Question

Mitchell took a math exam today.If he got 63 out of 84 questions correct, what percentage did Mitchell get wrong?

Answer 1

The answer is x = 25%

Explanation:

84 represents 100% of the questions.

63 represents x% of the correct answers.

x = (63x100)/84

x = 6300/84

x = 75% correct answers.

percentage of the wrong answers:

100% - 75% = 25%

Answer 2

Answer: The required percentage is 25%.

Step-by-step explanation: Given that Mitchell took a math exam today and got 63 out of 84 questions correct.

We are to find the percentage of questions that Michael got wrong.

The number of questions that Michael got correct, n = 63 and

the total number of questions, N = 84.

So, the number of questions that Michael got wrong is

N - n = 84-63 = 21.

Therefore, the percentage of questions that Michael got wrong is

`p=(N-n)/(N)*100\%=(21)/(84)*100\%=(100)/(4)\%=25\%.`

Thus, the required percentage is 25%.
