There are 320 ducks in a pond. On the first night 1/4 of them get eaten by a fox. On the second night 1/6 of the remaining ducks fly away, and on the third night 30 percent are stolen. How many ducks remain after the three nights?
Please answer and provide answer explanation.
140
First night:320(1 / 4) = 80.

320 - 80 = 240.

Second night:240(1 / 6) = 40.

240 - 40 = 200.

Third night:200(.

30) = 60.

200 - 60 = 140 ducks remain.

.

The answer is 140
