Answer:
All numbers that are 12 or less.
Step-by-step explanation:
This is indicated by the ≤ sign - it is looking for a number less than or equal to 12. The only number equal to 12 is 12, and the rest is below that value. So, the possibilities are:
12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1, -2, -3, and all of the other negative numbers up to infinity.
