This is a math problem that is puzzling me, as I am not sure why the math works in this case. So for all you math people out there why does the math work?
An old farmer died leaving his 17 horses
to his 3 sons.
When his sons opened up the will it
read:
‘My eldest son should get 1/2 (half) of
total horses;’
‘My middle son should be given 1/3rd
(one-third) of the total horses;’
‘My youngest son should be given 1/9th
(one-ninth) of the total horses.’
As it’s impossible to divide 17 into
half or 17 by 3 or 17 by 9, the three sons started to fight with each other.
So, they decided to go to a farmer
friend who they considered quite smart, to see if he could work it out for
them.
The farmer friend read the will
patiently, and, after giving due thought, brought one of his own horses over
and added it to the 17.
That increased the total to 18 horses.
Now, he divided the horses according to
their father’s will.
Half of 18 = 9. So, he gave the eldest
son 9 horses.
1/3rd of 18 = 6. So, he gave the middle
son 6 horses.
1/9th of 18 = 2. So, he gave the
youngest son 2 horses.
Now add up how many horses they have:
Eldest son 9
Middle son 6
Youngest son 2
TOTAL = 17
This leaves one horse over, so the
farmer friend takes his horse back to his farm
