EXAMS:
63+83+93=293. We take 293 and divide that by the 3 exams taken to find the average which is 79.66%. Since this is 50% of your grade, we multiply 79.66 by 0.5 and come out with 39.83%.

HOMEWORK:
11/14=78%
78+78+78+78+78+70+80=540. Again we take 540 and divide that by 7 to come up with an average score of 77.14%. Since this is 40% of the grade, we multiply 77.14*0.4 to come up with 30.85%.

TOTAL:
Now we just add them up, so 39.83+30.85=70.68%. In your PM you sent me, you asked what if you scored an 85% in what ever category accounts for the remaining 10%. Again we just work out the math, 85*0.1=8.5%. Now we add 8.5+70.68 to come up with 79.18% final grade.
