Astudent received an 82% on an exam. if there were 50 questions on the exam, which ratio would show the number of questions answered correctly?

Steps: 

1. First, divide 82 by 100, since this is what you would have originally gotten with the ratio. 
82 ÷ 100 = 0.82

2. Then multiply it by 50 (since this is how many questions were on the test)
0.82 × 50 = 41 < (the number of questions answered correctly)

3. Now that you have the two numbers you need, you can assemble the ratio. 

41/50

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
