Answer:
2:5 (2 cups of water to 5 cups of flour)
Explanation:
1. The ratio is explained in the sentence: "For every two cups of water she mixes in five cups of flour to make the paste."
- 2 cups of water for every 5 cups of flour
2. The question asks for cups of water first, then cups of flour. Therefore, the number of cups of water will come before the colon, and cups of flour after the colon. Knowing this, we can write the information given in ratio form.
