Per stirpes receive one-third (all of "D"s one-third share). Under "per capita", the two-thirds remaining after "C" 's one-third share was taken would be divided equally among all three children of "B" and "D". (Two-thirds = six ninths) Each would receive two-ninths: "B1", "B2", and "D1" would all receive two-ninths. "Notes:" In many U.S. states, such as New York, a statute has modified the "per stirpes" approach and utilizes instead a per capita with representation approach (also known as modern American per stirpes). Under the per capita with representation approach, the number of branches is determined by reference to the generation nearest
Parts-per notation Since it is usually not stated which quantity is used, it is better to write the unit as kg/kg, mol/mol or m/m (even though they are all dimensionless). The difference is quite significant when dealing with gases and it is very important to specify which quantity is being used. For example, the conversion factor between a mass fraction of 1 ppb and a mole fraction of 1 ppb is about 4.7 for the greenhouse gas CFC-11 in air. For volume fraction, the suffix "V" or "v" is sometimes appended to the parts-per notation (e.g., ppmV, ppbv, pptv). Unfortunately, ppbv and
