28 white ducks swimming in pond 2*(28 white ducks) = 56 brown ducks flew and landed in pond (28 white ducks)/2 = 14 white ducks remained in the pond
Ducks remaining in the pond (at this point): (14 white ducks) + (56 brown ducks) = 70 ducks in all
After calculating, there are 70 ducks remaining in the pond. This includes 14 white ducks and 56 brown ducks. The process included adding the brown ducks and then subtracting half of the white ducks that left.
