A
Once upon a time there was an old man, who had three sons. Calling them together, he said, "Sons, my end is near. To my oldest son I give him half my camels, to my second one-third, and to my youngest one-ninth." Then he died.
The old man had seventeen camels, and the three brothers did not know how to share them as their father said. It seemed that they must have to kill one camel to share it by pieces or do not follow their father's words. At last they went to their father's old friend and asked him for help. As soon as he heard their story, the old man said, "I will help you. I am old. I have only one camel, but take it — it is yours."
The three sons took the old man's camel and thanked him. They found that it was easy now to divide the camels as their father had wished. The oldest took nine camels; the second took six; and the youngest took two.
Only when each had received his share did they discover that there was one camel left. So, they returned the camel to their father's friend with many thanks.
