Answer:
80%
Step-by-step explanation:
Percentages are usually found by taking the value that you want to find and dividing it by the whole amount (100% of the total value available). In this case, getting 100% on the test would mean getting 120/120, because 120 points is 100% of the points available. However, the student only got 96 points out of the whole 120 points, so to find the percentage, you do 96/120 to find what part of 96 comes out of 120. Then to convert to percentage, multiply that value by 100 to get your finale value.
