Who inherits a woman who died leaving a full brother and two sisters, and what is the share of each heir?

If a woman passes away leaving behind a full brother and two full sisters, her estate is to be distributed among her three full siblings, with the male receiving the share of two females, in accordance with the Almighty's saying: (And if there are brothers and sisters, male and female, then for the male will be the portion of two females) [An-Nisa/176]. There is nothing for any heir who passed away before her. The estate is to be divided into four shares: two shares for the brother, and one share for each of the two sisters.
