How is the inheritance divided among the husband, the mother, three sisters from the father's side, and two sisters from the mother's side?

If a woman leaves behind no heirs except her husband, her mother, two uterine sisters (sisters from the mother's side), and several paternal sisters (sisters from the father's side), then the inheritance is divided into thirty shares: the husband receives one-half (nine shares), the mother receives one-sixth (three shares), the two uterine sisters receive one-third (six shares), with three shares for each, and the paternal sisters receive two-thirds (twelve shares), with four shares for each.
