Once upon a time there was a rich man with three sons under his knees. On his deathbed, he called his three sons to the three beds, and in addition to dividing the other family property, there were 11 horses to be divided. He left his last words: the eldest accounted for one-half of all the horses, the second accounted for a quarter, and the third accounted for only one-sixth, and the rich man left for the west. The brothers finished the rich man's affairs and prepared to divide the horses. This is difficult for everyone, according to the rich man's last words to divide, then these 11 horses are divided? You can't slaughter the horses and divide them up. When he was in trouble, a friend of the rich man's life learned of the rich man's fairy tour and specially rode a horse to comfort the family of the forgotten friend. When he learned that the three brothers were struggling over the division of horses, he lent them the horse he had come to. As a result, the brothers smoothly divided their respective horses according to the rich man's last words, and after the division, there was just one horse left, and finally returned the horse to the rich man's friend.
