Three chickens weighed in pairs 
20150901 

From Shelly: My son brought home a problem of 3 chickens of different weights listing their weights in different groupings of 2. We are to determine the weight of all three together. I think it's a ratio problem, but I am too far removed to formulate a plan to teach him how to solve it. Answered by Robert Dawson and Penny Nom.
