How is the estate of a woman who left behind two sons, a daughter, and their father divided?

The inheritance, when a woman dies and leaves behind a husband, two sons, and a daughter, is divided as follows: The husband receives one-fourth due to the presence of offspring, as stated in the verse: (And for you is half of what your wives leave if they have no child. But if they have a child, for you is one fourth of what they leave). The remainder goes to the children, with the male receiving the share of two females, as stated in the verse: (Allah instructs you concerning your children: for the male, what is equal to the share of two females). The inheritance is divided into 20 shares: The husband's share is 5 shares, the daughter's share is 3 shares, and each son's share is 6 shares.
