The two-digit number
1 is divisible by 9.
9.
To find a two-digit number that is divisible by 9, we need to think about the properties of numbers that are divisible by 9.
One property is that when you add up the digits of a number that is divisible by 9, it also must be divisible by 9.
So, let's find a number whose digits add up to 9:
- 18: 1 + 8 = 9, so it is divisible by 9.
- 27: 2 + 7 = 9, so it is divisible by 9.
- 36: 3 + 6 = 9, so it is divisible by 9.
- 45: 4 + 5 = 9, so it is divisible by 9.
- 54: 5 + 4 = 9, so it is divisible by 9.
- 63: 6 + 3 = 9, so it is divisible by 9.
- 72: 7 + 2 = 9, so it is divisible by 9.
- 81: 8 + 1 = 9, so it is divisible by 9.
So, any two-digit number formed by these combinations will be divisible by 9. For example, 18, 27, 36, 45, 54, 63, 72, and 81 are all two-digit numbers divisible by 9.
To fill in the blank, we can choose any of these numbers as the answer.
