Divisibility Test: Is 685 Divisible by 9?

To determine whether the number $685$ is divisible by $9$, we use the divisibility rule for $9$: a number is divisible by $9$ if the sum of its digits is divisible by $9$.

Let's calculate the sum of the digits in $685$:

$6 + 8 + 5 = 19$

Now, we check if $19$ is divisible by $9$. In this case, $19 \div 9 = 2$ with a remainder of $1$.

Since $19$ is not divisible by $9$, the number $685$ is also not divisible by $9$.

Therefore, the answer to the problem is that $685$ is not divisible by $9$. Hence, the correct choice is:

: No
