Answer:
D: 9 and 12
Explanation:
The way I worked out the soultion is by seeing if they are multiples, how I did that was simply by going on to a multiples chart or calculator and seeing if 9 and 12 each had the numbers 72, 108, and 180 on them and once I did I knew that was the answer. The other answers did have at least one of the numbers as an answer but they didn't have all three, the only one that did was answer D.
