Which of these numbers exactly divide by nine? 116 713 495 640 or 360

I assume the question means that it is nine divides it:

116/9 = 12 8/9

713/9 = 79 2/9

495/9 = 55

640/9 = 71 1/9

360/9 = 40

An easier way to do it would be adding all the digits and see if that divides nine:

1+1+6 = 8, not

7+1+3 = 11, not

4+9+5 = 18, yes

...

I will explain why it works if you are interested.

116/9 = 12.88

713/9 = 79.22

495/9 = 55

640/9 = 71.11

360/9 = 40

it would be 495 and 360
