Grades: 44/50, 84/100, 200 (assuming this is out of 200), 0/?, 25/?, 91/?
We need to know the maximum possible score for the grades of 0, 25, and 91 to calculate the class grade. Let's assume they are all out of 100 for now.
Calculating percentages:
* 44/50 = 88%
* 84/100 = 84%
* 200/200 = 100%
* 0/? = 0% (assuming a max score of 100)
* 25/? = 25% (assuming a max score of 100)
* 91/? = 91% (assuming a max score of 100)
Finding the Class Grade (Assuming all are out of 100):
To find the class grade, we need to add all the percentage scores and divide by the number of grades (6):
(88 + 84 + 100 + 0 + 25 + 91) / 6 = 488 / 6 = 81.33%
Therefore, if all grades are out of 100, the class average is approximately 81.33%. However, this is contingent on the unknown maximum scores for the 0, 25, and 91 grades. Provide those maximum scores for a more accurate calculation.
