Answer:
The new values for the first to the third original partners is 27.7% each.
Step-by-step explanation:
At first, given that the law firm had 3 partners and was worth $ 1,500,000, it could be said that each of them had 1/3 part of the firm, worth $ 500,000 each.
Now, with the addition of a new partner who brought with him a capital of $ 300,000, the value of the firm becomes $ 1,800,000. In this context, the original partners go from having 1/3 of the firm each to having 5/18 of it. Now, in percentages, these partners went from having 33.3% each to having 27.7% of it, while the new partner entered the firm with 16.6% of its value.
