i would never pour bag mix for a surface job but for fence posts you cant beat the convenience of just opening a bag and mixing it. no messy hauling and you can take back what you dont mix up...if you are dead set on mixing your own you can get by with a 3 sand, 4 gravel and 1 cement mix...this will be strong enough for posts...
3 parts of sand, 2 of gravel and 1 of cement is the old standby for mixing your own concrete, if not using a readi-mix product.
use quickcrete half a bag to each post is fine put it in dry then hose some water on it if it need more water to cure itwill pull it from the ground this is the easy way if you are going to do it the hard way it is one bag portland cement one five gallon bucket of water and 15 shovelfulls of sharp sand dont use playsand the granuals are round and it wont bond correctly
I buy premix just add a little bit of water stir with a shovel and avoid all the problems of mixing to the right ratio.
