What is the share of each heir from the estate of the deceased - female - who left behind: a mother, a full brother, and a full sister?

If the deceased left no heirs other than those mentioned, then the mother receives one-sixth due to the presence of a group of siblings, as Allah Almighty says: "If he has brothers [and sisters], the mother will have a sixth." The remainder goes to his full brother and full sister by ta’sib (residuary heirship), with the male receiving the share of two females, as Allah Almighty says: "And if they are brothers and sisters, male and female, then the male will have the share of two females." The inheritance is divided into eighteen shares: the mother receives three shares, the full brother ten shares, and the full sister five shares.
