Thread: Weighted Average

I have the following formula:
E = (b+4p+w)\6

I Use the weighted average with the following weights for b, p and w respectively: 1:5:2

Given values​​:
b = 5
p = 15
w = 18

How do I find the value of E ?

The answer is:
14,43

try

b = 5 (1/(1+5+2))

p = 15 (5/(1+5+2))

etc..

I've tried and not of the correct value
b = 5/8
p = 75/8
w = 9/2

E = 341/48 = 7,1041666
