Would it be correct to calculate the weighted average of the following scores by multiplying the score by the weight for all and then adding this up, or am I supposed to divide by something?

Ex.

Intern had 4 rotations worth 20% of overall score

Score %

R1 4 20%

R2 4 20%

R3 3 20%

R4 3 20%

there are 10 teammate qualities/dimensions that they are rated on

Score % Weight

D1 4 2%

D2 4 2%

D3 4 2%

D4 3 2%

D5 5 2%

D6 4 2%

D7 4 2%

D8 3 2%

D9 4 2%

D10 4 2%

Would I find the weighted avg by doing the following?:

(R1*.2)+(R2*.2)+(R3*.2)+(R4*.2)+(D1*.2)+(D2*.2)... ..+(D10*.2)

Thanks
