Answer: B 75%
To find the percentage Mitchell got wrong, we need to subtract the number of questions he got right from the total number of questions and then divide by the total number of questions:
Total questions = 84
Questions correct = 63
Questions wrong = Total questions - Questions correct = 84 - 63 = 21
Percentage wrong = (Questions wrong / Total questions) * 100
Percentage wrong = (21 / 84) * 100
Simplifying this, we find:
Percentage wrong = 0.25 * 100 = 25%
Therefore, the correct answer is A) 25%
To find the percentage of questions that Mitchell got wrong, we need to subtract the number of questions he got right from the total number of questions and then divide that by the total number of questions.
The total number of questions is 84, and Mitchell got 63 questions correct. So, the number of questions he got wrong is 84 - 63 = 21.
Now, we can calculate the percentage:
Percentage of questions Mitchell got wrong = (Number of questions wrong / Total number of questions) x 100
= (21 / 84) x 100
Simplifying this, we get:
= 0.25 x 100
= 25
Therefore, Mitchell got 25% of the questions wrong.
The correct answer is A) 25%
