How is an inheritance divided among: a father, a mother, a husband, two daughters, and two paternal half-brothers?

If a woman's heirs are only her mother, father, husband, and two daughters, then:

Her mother gets one-sixth (two shares).

Her father gets one-sixth (two shares).

Her husband gets one-fourth (three shares).

Her two daughters get two-thirds (eight shares, four for each).

Her paternal half-brothers do not inherit due to the presence of the father.

The case is an awl from twelve to fifteen, so the inheritance is divided into fifteen shares.
