This means that the stupid father is playing with those three stupid sons.

If I say to you, "We earned 1 0,000 yuan together, I made a great contribution and got 5,000 yuan;" How about giving you the remaining 4000 yuan? "

Can you agree? You must ask, "No, 5000+4000=9000, not 10000!" Where is 1000? "

If I had been there when the cows were distributed, I would have asked the same question: "No, 1/2+1/9 =17/18, not1! Where is118? "

Now that we know that this old guy is playing us.

Can't be divided in the usual way.

So it is distributed in proportion.

1/2 : 1/3 : 1/9 = 9:6:2

This can be solved.
