If you are dividing the money into 3 shares, in proportion 3:5:9, there are 3+5+9 = 17 parts.  Divide the whole amount by 17, then multiply by the number of parts in each share.  For example, if the amount to be split was $170, each share would be $170/17 = $10.  The first person gets 3 shares = 3*$10 = $30.  The second person get 5 shares = 5*$10 = $50.  The third person gets 9 shares = 9*$10 = $90.  If we add the three together, $30 + $50 + $90 = $170, just as it should.
