What is the weighted average?
if a=50%,b=25%,c=20%,d=5%.
Value of a=136.5/255,
b = 75/75
c =19/20
d = 30/30.
I keep getting different answers. Can someone explain the right way to do this?

If you had four NUMBERS, A, B, C, and D, with "weights" 50%, 25%, 20%, 5%, respectively, then the "weighted average" would be .5A+ .25B+ .2C+ .05D.
[.5(136.5/255) + .25(1) + .2(19/20) + .05(1)] / [136.5/255 + 1 + 19/20 + 1] = .2496....Quote:
