Question: Can you explain how to solve this math problem: Tracy feeds each of her two dogs 1.5 cups of food per meal. She feeds her dogs thrice a day. How many pounds of food do her two dogs consume if 1 pound is equal to 2.25 cups?
Answer: 
Each dog consumes 1.5 x 3 = 4.5 cups of food a day.
In pounds, this is equal to 4.5/2.25 = 2.
So both consume 2 x 2 = 4 pounds of food.
