Final answer:
To find the amount of flour in one serving of waffles, divide the total amount of flour by the number of servings. In this case, there are 2/5 cups of flour in one serving of waffles.
Step-by-step explanation:
To find the amount of flour in one serving of waffles, we need to divide the total amount of flour by the number of servings. In this case, the recipe calls for 1/5 cup of flour to make 7/10 serving of waffles. So, to find how many cups of flour are in one serving, we can set up the following proportion:
1/5 cup flour / 7/10 serving = x cups flour / 1 serving
To solve for x, we can cross-multiply and then divide: 1/5 * 1 serving = 7/10 * x cups flour
7/10 * x = 1/5 * 1
x = (1/5 * 1) / (7/10) = 2/5 cups
Therefore, there are 2/5 cups of flour in one serving of waffles.
