Step-by-step explanation:

There is no data given

1000, 2000, 3000, etc are the 4-digit numbers which when divided by 1000, give whole number answer.

Step-by-step explanation:

Scott divides some 4- digit numbers by 1000 and his answer is a decimal every time.

I think Scott is wrong and the reason is that if we try to divide those 4-digit numbers which are multiples of 1000, i.e. 1000, 2000, 3000, 4000, ... etc. with 1000 then only you will get a whole number answer. (Answer)
