There once was an old goat herder who passed away leaving 17 goats to his 3 sons. To his first son he left half the goats, to his second son he left a third of the goats, and to his youngest son he left a ninth of the goats.
After his passing the sons fought over the goats and how to divide or butcher them.
With no resolution in sight they went to the edge of the city to speak with a wise woman who had traded goats for many years. Her solution was to give them her last goat. They then divided the goats evenly and returned her goat to her.
And everyone received more than they were promised.
