The wife will gain her dowry(Mahr) from the property because it's a debt + one 8th of the property because the dead person had children.
Then the rest of the property will be divided between the children with the formula of: "The share of boys is twice the share of girls"
وَإِن كَانُوا إِخْوَةً رِّجَالًا وَنِسَاءً فَلِلذَّكَرِ مِثْلُ حَظِّ الْأُنثَيَيْنِ
But if there be [several] brothers and sisters, then for the male shall be the like of the share of two females. (4:176)
