Need help with this math!

[unclejohn]

So i have a mixture that is 32% protein, which i plan to mix with wheat and oats, which are both 12% protein.

so i mix equal parts 32% - 12% - 12%...where will my protein percentage be? I arrived at 17% protein but I am not good at math.

by equal parts i mean like, 10 pounds 32% - 10 pounds 12% - 10 pounds 12% (or however much weight, this is just an example)

Don't know if I'm right, but I think 18.7 % ?

Since you are using equal weights of the 3, average the total of the 3 percentages.

32 +12+12=56 / 3 = 18.6666

okay thank you! I was close enough I guess, so I will mix it 1/3 then.
