Question 550104: I have 11 classes. In 6 classes I received an A, in 4 classes I received a B and in 1 class I receive a C. I tried dividing each into 100%, but something is not working. My answer came out to 60% of A's, 40% of B's and 1% for C's. But how can this be when the total is 100%? Please tell me if I did this right or how do I figure out what percentage of A's, B's and C's I received?
Thank you
