Answer:
1080
Explanation:
Whenever you multiply a number by 1/2, it halves the number. Such as when you multiply 2 by 1/2, it will be one. Or if you multiply 3 by 1/2, you get 1.5. But when you're doing the opposite to see what to multiply by, all you have to do is double the number, or multiply it by 2.
