Winnie-the-Poo, Piglet, Rabbit, and Donkey Eeyore emptied a barrel of honey. Piglet ate half of what Winnie-the-Poo ate, Rabbit ate half of what Winnie-the-Poo did not eat, and Donkey Eeyore got only a tenth of the barrel. What part of the barrel did Rabbit get?
Piglet ate half of what Winnie-the-Pooh ate, Rabbit - half of the remainder. This means that Piglet and Rabbit together ate half of all the honey. The second half was eaten by Winnie-the-Pooh and Eeyore. Eeyore ate one-tenth, so Winnie-the-Pooh ate $1 / 2 - 1 / 10 = 2 / 5$ of the barrel. Then he did not eat $3 / 5$ of the barrel, and Rabbit - half of this amount, that is, $3 / 10$.

## Answer

$3 / 10$.
