Question 119105
The wife gets 1/2, leaving 1/2 as a remainder.


The older child gets 1/2 of the remaining 1/2, or 1/4, leaving 1/4 as a remainder.


The younger child gets 1/2 of the remaining 1/4, or 1/8, leaving 1/8 as a remainder.


The two cousins split the remaining 1/8, each getting 1/16.


Check:
{{{1/16+1/16+1/8+1/4+1/2}}} = {{{1/16+1/16+2/16+4/16+8/16}}} = {{{16/16}}} = {{{1}}}
