Answer: 
75%
Step-by-step explanation:
If Mitchell took a math exam and got 63 out of 84 questions correct, that would turn into the fraction: 63/84
In order to convert this to a decimal, you divide 84 by 63 (since every fraction is a division problem), and get 0.75. 
When you change decimals into percents, you move the decimal point two times to the right. So, that would be 75.
Then you add the percent symbol and you're done!
I hope that helped :)
