How is an inheritance divided among a deceased's three full brothers, a mother, and five full sisters?

If the deceased leaves behind only a mother and full siblings (brothers and sisters), then the mother receives one-sixth (1/6) as a prescribed share due to the presence of inheriting descendants. The remainder goes to the full brothers and sisters by way of ta'seeb (residuary inheritance), with the male receiving the share of two females. The inheritance is divided into 66 shares: the mother receives 11 shares, each full brother receives 10 shares, and each full sister receives 5 shares. Inheritance matters should be referred to Sharia courts to verify the existence of other heirs, bequests, or debts.
