The will of a deceased collector of antique automobiles specified that his cars be left to his three children. Half were to go to his elder son, ⅓ to his daughter, and ⅟9 to his younger son. At the time of his death, 17 cars were in the collection. The administrator of his estate borrowed a car to make 18. Then he distributed the cars as follows:

Elder son: ½ (18) = 9 Daughter: ⅓ (18) = 6 Younger son: ⅟9 (18) = 2

This totaled 17 cars, so he then returned the borrowed car. Where is the error in this problem?

So, might be I'm too tired or too stupid, please help.

Сайт же русский. А ответ такой:

Half were to go to his elder son, ⅓ to his daughter, and ⅟9 to his younger son.

1/2 + 1/3 + 1/9 = 9/18 + 6/18 + 2/18 = 17/18, то есть если бы они распределяли 17 машин, их бы пришлось пилить и 17/18 машины не досталось бы никому, а так они взяли дроби от 18 машин и как следствие, получили целые количества машин, из которых одна целая машина оказалась «лишней».

1/2+1/3+1/9=17/18 which is not equal to one.
