How many ducks are eaten on the first night? ** First night:320(1/4)=80
How many ducks are left after the first night? ** 320-80=<<320-80=240>>240
How many ducks fly away on the second night? ** Second night:240(1/6)=40
How many ducks are left after the second night? ** 240-40=<<240-40=200>>200
How many ducks are stolen on the third night? ** Third night:200(.30)=60
How many ducks remain after the three nights? ** 200-60=<<200-60=140>>140 ducks remain
