• A. divisible
• B. not divisible
• C. equivalent

Answer 1

The correct option is B not divisible

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> If we add the sum of the digits of 664, we get as 16 (6+6+4 = 16). 16 is not divisible by 9. We know that if the sum of the digits of the number is divisible by 9 then that number is divisible by 9. Therefore we can say that the number 664 is not divisble by 9.
