What are the shares for three dispersed sisters, each half-free, accompanying a half-free mother and an uncle ('amm)?

Book of Inheritance Shares (Farā'id)
Primary text
The sister related through both parents (father and mother) receives one-fourth. The sister related only through the father receives one-sixth. The sister related only through the mother receives one-half of the one-sixth share. The mother receives one-third, as she is only prevented from her share by two brothers or sisters, and the freedom in two sisters is not complete. The uncle receives the remainder.
Supporting text
If there is one full free sister and another sister half-free, the mother still receives one-third based on the established reasoning.
