A tough cookie to solve


The witch used 20 biscuits to decorate the roof of her house.
She lined them up and put icing on every second biscuit.
Then, she put a cherry of every third biscuit.
Then, she put a chocolate button on every fourth biscuit.

How many biscuits had no decorations on top?
Did any biscuits have all three decorations on top?
