How is the inheritance divided among the father, the mother, three daughters, a full brother, and two full sisters?

The father gets one-sixth and the mother gets one-sixth due to the presence of children. The daughters get two-thirds. The full brothers get nothing because they are excluded by the father. The inheritance is divided into 18 shares: 3 shares for the father, 3 shares for the mother, and 4 shares for each daughter. Inheritance matters should be referred to the Sharia courts for investigation.
