Answer: 6
Step-by-step explanation:
The answers right because, if he used only twelve of them and he used 1/2 of twelve then we just divied 12 by 1/2. And that means we are dividing 12 by 2, (because 1/2 equals 2,) And that equals 6. To make sure we are correct we can multiply 6 by 2 and that equals 12.
