Question about "dilutions"

by Jane

Rx: Prostaglandin E 10mcg/ml
If the stock container of Prostaglandin E is 100mg/ml, how many 9-ml dilutions are required to prepare the ordered concentration? The answer key to my test gives the answer as FOUR dilutions? How is this problem solved? Any help you can give me will be greatly appreciated!
