Ketubot 93: The Complication of Additional Players in Financial Allotment

A math word problem, as it were, beginning with a man who was married to 3 women, who each had ketubot of different value - and the man died. And other comparable scenarios, with payments to be puzzled out. With parallels to business investments and liquidation. Plus, how the Amoraim flesh out the details of the mishnah. Also, a deeper dive into the parallel of shared business investment, with uneven contributions. When are their returns identical, despite the uneven contributions, as per Shmuel, and when are their returns proportional? Plus, another mishnah - a man who's married to 4 women, and dies. How are those women each to collect their respective ketubot, given the other women's presence? Note that the Jerusalem ketubot included not only the date, but also the time of the day, as salient for the extreme case to determine policy.
