Question

What is the smallest counting number more that 100 and a multiple of 9?

Answer 1

It would be 108 that’s the smallest, correct me if I’m wrong but I hope this helps

Answer 2

108

Explanation:

A number is divisible by 9 when its sum of digits is divisible by 9. Hence you're looking to add a digit to the digit 1 that makes the total be 9. That digit is 8.

When you put 8 in the units place of the number with 1 in the hundreds place, you get the smallest number greater than 100 that is divisible by 9: 108.
