Let's note that 1/17 is a repeating decimal. 

1/17=0.¯0588235294117647

 

There are 16 repeating digits in the decimal. 

Dividing 4000 by 16, we get

4000/16=250

 

Since it is divisble, then we can conclude that the last digit of the repeating decimal is the correct answer. 

Thus, 7 is the final answer. 

 

Thanks! :)
