What is the share of each heir from the estate of the deceased who has six full brothers' sons, one full sister, one paternal sister, and three full brothers' daughters?

Nieces have no share in the inheritance. If the deceased left no heirs except those mentioned, her full-sister receives one-half as a prescribed share, and her paternal half-sister receives one-sixth to complete the two-thirds. The remainder goes to the full-brother's sons by virtue of 'asaba (agnatic relationship), equally. The estate is divided into eighteen shares: nine shares for the full-sister, three shares for the paternal half-sister, and six shares for the full-brother's sons, with each of them receiving one share.
