An elderly farmer died and left 17 cows to his three sons. In his will, the farmer stated that his oldest son should get 1/2, his middle son should get 1/3, and his youngest son should get 1/9 of all the cows. The sons, who did not want to end up with "half cows", sat for days trying to figure out how many cows each of them should get.
One day, their neighbour came by to see how they were doing after their father's death. The three sons told him their problem. After thinking for a while, the neighbour said: "I'll be right back!" He went away, and when he returned, the three sons could divide the cows according to their father's will, and in such a way that each of them got a whole number of cows.
When my father died he had 5 dogs.
In his will he wrote that I would have one third of the dogs, my sister would have one half of the dogs.
But me and my sister wouldn't kill any of the dogs so we asked our neighbour how to do. He suggested a solution how to divide the five dogs so I could have one third of them and my sister one half of them without killing a single dog.
How did we do it? 😕
