Question 1038693
If it is $150,000 and I understand the question properly, 
3 get 20,000
That is 20,000/150,000 or 2/15, when all the zeros cancel out.
2/15 is 15 divided into 2.00000, and that is 13.3%, 13.33333333% if you wish.
The last gets what is left over, which is $90,000, and that is 60% of $150,000
Three get 13.3%, one gets 60%, and the last 0.1% is rounding error.
