Final answer:
To find out how many cups of water will be required for 2/5 cups of oats, you can set up a proportion based on the given information. One cup of water is required for every half cup of oats. By solving the proportion, you will find that 4/5 cup of water will be required for 2/5 cup of oats.
Step-by-step explanation:
To find out how many cups of water will be required for 2/5 cups of oats, we can set up a proportion based on the given information. One cup of water is required for every half cup of oats. So, we can set up the proportion:
1 cup of water / (1/2 cup of oats) = x cups of water / (2/5 cup of oats)
We can solve this proportion by cross-multiplying: 1 cup of water * (2/5 cup of oats) = (1/2 cup of oats) * x cups of water. Simplifying, we get: 2/5 cup of water = (1/2 cup of oats) * x cups of water.
To solve for x, we can divide both sides of the equation by (1/2 cup of oats): 2/5 cup of water / (1/2 cup of oats) = x cups of water. Simplifying, we get: 4/5 = x. Therefore, 4/5 cup of water will be required for 2/5 cup of oats.
