So, for example suppose the score on the first assignment was 80 out of a possible 90 and the score on the second assignment was 100 out of a possible 120. To scale each of them so they are out of a possible 100 I would do the following
The first assignment is weighted 65% 0r 0.65 and the second assignment is weighted 35% or 0.35 so the weighted sum, out of a possible 100 points is
I hope this helps,
