There were 67 white ducks swimming in a pond, twice as many brown ducks flew in and landed in pond then half of white ducks flew hany many ducks remained in the pond

Hello! So, there were 67 white ducks and 2 times as many brown ducks flew in the pond. 67 * 2 is 134. Then, half of the white ducks flew out. There were 67 white ducks. 67/2 is 33.5, but you can’t have half of a duck fly away. We would have to round up, so that would mean 34 white ducks flew out, because 33.5 rounds up to 34. 134 - 34 is 100. There are 100 ducks that remain in the pond.
