Answer:
18
Step-by-step explanation:
18 divided by 2 gives you 9 and 18 divided by 9 gives you 2.
Some other numbers would be, 36, 81, and other numbers that are multiplied by 9 and are even.
[tex]2 = 2 \\ 9 = 3 \times 3 \\ \\ = 2 \times 3 \times 3 \\ = 18[/tex]
so 18 is the number which is divisible by 2 and 9
