Answer: No it's not

Step-by-step explanation:

To find whether 89987794 is divisible by 9 add all its digits first

So, 8 + 9 + 9 + 8 + 7 + 7 + 9 + 4 = 61

Now, is 61 divisible by nine? It's not, so it's not divisible by 9

Remember this: if the sum of the digits of a number is divisible by 9, then it's divisible by 9
