Use drawings, words, or numbers to explain how you got your answer.

Mr. Greenwill looked out on his farm and saw rabbits every where. He said, "I think there are about 1280 rabbits in that paddock. They have been doubling in number for the last seven years."

How many rabbits were in the paddock seven years ago?






























































Answer for sheet # 158

If now there are 1280 rabbits, then a year ago there were 640, two years ago there were 320, three years ago there were 160, four years ago there were 80, five years ago there were 40, six years ago there were 20 and seven years ago there were 10.

So seven years ago there were only 10 rabbits in Mr. Greenwill's paddock.
