Uncle Zhang raised some chickens, ducks and geese in his family. Chickens account for half of the total number and ducks account for one third of the total number

Let the total number of chickens, ducks and geese be X
The number of chickens is 1 / 2x
The number of ducks is 1 / 3x
The number of geese is X-1 / 2x-1 / 3x
So, chicken: Duck: Goose = 1 / 2x: 1 / 3x: (x-1 / 2x-1 / 3x)
=1/2:1/3:1/6
=3:2:1
A: the ratio of chickens, ducks and geese is 3:2:1
