Biscuit Decorations

Stage: 1 and 2 Challenge Level: Challenge Level:1

Andrew decorated $20$ biscuits to take to a party.

He lined them up and put icing on every second biscuit.

Then he put a cherry on every third biscuit.

Then he put a chocolate button on every fourth biscuit.

How many other biscuits had no decoration? Did any biscuits get all three decorations?
