ALERT: THIS IS A MATH PROBLEM

Here's how it works, each day I dump out all the skittles and whatever side faces no 'S' then I eat it. Next day I do the same till there's none left.

And no I can't actually buy a big bag of Skittles and try it. So how would I explain this in a paragraph?

After that she met with a wolf, who demanded 1/4 of remaing cakes.

After that she met with a bear, who demanded 1/3 of remaing cakes.

1/2 of remaining cakes the girl ate herself, and delivered 1 cake to her grandmother.
