An old farmer died.Just before that ,he wrote a testament stating how his property should be shared:
My eldest son will receive one half of my sheep. My second son will receive one thid of my sheep .My youngest son will receive one ninth of my sheep.
Now the problem is that one sheep just died last week and three sons are left with 17sheep to share.
Then how they should do ?

借来一头羊，这样有18头羊
老大拿一半，9头
老二拿三分之一，6头
老三拿九分之一，2头
3个人一共取走9＋6＋2＝17头羊
多出来的1头还掉，那原来的17头羊就分好了
17+1 =18，18/2=9， 18/3=6，18/9=2， 9+6+2=17
老问题啊，为什么还要问呢？
17
18的一半是9
18的三分之一是6
18的九分之一是2
9+6+2=17
就算本来有18头羊也只能分出17头
这个都做了好几遍了
这好象是初二的暑假生活啊!!!
