Question 7663
First of all, the fractions add up too much. 1/2 + 1/7 + 2/3 > 1. In other words, you can't divide your wealth so that the portions are of the size 1/2, 1/7, and 2/3 of the original. Actually, the wife's portion and the servants portion even exceed his wealth, since even 1/2 + 2/3 > 1. There would then be no more left-over for his son and his dog. You might need to check the problem again to get the right figures.
