Question

Check the divisibility of $5476$ by $9$.

Answer 1

According to the divisibility by $9$:

A number is divisible by $9$, if the sum of its digits is divisible by $9$.

For example:

Consider the number $57384$

sum of digits $=5+7+3+8+4=27$, which is divisible by $9$. Therefore, the number $57384$ is divisible by $9$.

Now, we have $5476$,

the sum of digits of the number $5476$ $=5+4+7+6=22$,which is not divisible by $9$.

Thus, $5476$ is not divisible by $9$.
