1. Answer:

   198, 891, 918 – all divisible by 9

   Explanation –

   Divisibility rule – if the sum of the digits is divisible by 9, the number is divisible by 9.

   So, all of these digits have the same sum, which is 18, and 18/9=2

   therefore, we can see that all of these numbers are divisible by 9. Check it on a calculator if you aren’t sure 🙂
