Answer:
The son has a one-quarter interest, the daughter has a one-quarter interest, and the woman has a one-half interest.
Explanation:
First of all the man and the woman Boston land in both their names so we presume that they are tenants in common. Remember they were both on married at the time of the purchase. So after they purchased the land both of them were entitled to 1/2 each of this property.
Now this man gave out 1/4 to his son and another 1/4 to the daughter. The passion he has given out his his own share of the Land given that 1/4 + 1/4 = 1/2 which is his half of the Land.
Show ownership of this land not belongs to his son who owns 1/4, his daughter who also owns 1/4, and his wife who has 1/2 interest
