There are 72 chickens, ducks and geese in Liangliang's family, of which 4 / 9 are chickens, 3% of ducks and geese; 2. How many ducks and geese are there?

1. Because there are 72 chickens, ducks and geese, the number of chickens accounts for 4 / 9 of the total
So the number of chickens = 72x4 / 9 = 32
2. Total number of ah and E = 81-32 = 49
Because the ratio of ah and E is 3:2, that is, the total score of duck and goose is 2 + 3 = 5
Three for ducks and two for geese
So the total number of ducks = 3 / 5x45 = 27
Total number of geese = 49-27 = 22
