How is inheritance divided among three sons, three daughters, and one wife?

The inheritance of a deceased person who leaves behind only a wife, sons, and daughters is divided as follows: The wife receives one-eighth (1/8) due to the presence of a lineal descendant. The sons and daughters take the remainder by way of ta'sib (agnatic inheritance), with the male receiving the equivalent of the share of two females. The estate is divided into 72 shares. The wife receives 9 shares, each son receives 14 shares, and each daughter receives 7 shares.
