Answer: 5 batches of cookies
Step-by-step explanation: first, we know that 2 eggs, and 1 cup of water is one batch. Next we can put it in a ratio of 2:1, then we can see the next step of the problem. The 10 eggs and 7 cups of water. Since we have 10 eggs we can multiply our ratio 2:1, to 10:5. This is the max because we don’t have anymore eggs left to do 12:5, which is 6 batches. The answer is 5 batches
