At the county fair, farmers bring some of the animals to trade with other farmers. To make all trades fair a master of trade overseas all trades. Assume all chickens are of equal value all goats are of equal value and all pigs all equal value. • in the first trade of the day four goats were traded for five chickens
• in the second trade one pig was traded for two chickens and one goat
• In the thought trade for Melendy put up at three chickens against farmer Simpsons four goats.

Is this a fair trade? If not who’s animals are worth more? How could this be made into a fair trade?
