convert to 3nf

i need help taking this table to third normal form.

Part(PartNum, Description, OnHand, Class, Warehouse, Price,
(OrderNum, OrderDate, CustomerNum, CustomerName, RepNum,
LastName, FirstName, NumOrdered, QuotedPrice))

you need part, customer and order tables.

since it looks like an assignment i am only giving you a hint, got a deal with your professor :D.
