Answer:
ill try my best it's been 4 years since I learned this
Explanation:
The answer is 9 because each dog is eating 1.5 or 1 1/2 cups of dog food to get the 1.5 or 1 1/2 you must divide 6 by 4.
Now take that 1 1/2 and multiply it by 2 since where adding two dogs that equals 3
3 + 6 =9
I'm so sorry if this is wrong
