Percentage of business acquisition question

Question

Partner A owns 34 % of a business, Partner B owns 22.75% of the business, Partner Z wants to sell his 28.75% of the business. What percentage partner A and B would get proportionally when acquiring Partner Z 28.75% of the business??

Answer 1

34/(34+22.75) = 34/5675)= about 60% of Z's 28.75 = A's proportionate share of 17.1%

B gets about 40% of Z's 28.75 = about 11.5%
