Final answer:
None of the provided statements is correct; for each cup of water, there would be approximately 1.28 cups of flour, which is 1 5/18 cups in simplest form.
Step-by-step explanation:
The student's question asks for the correct statement regarding the proportion of flour to water used in a chef's dough recipe. The recipe uses 23 cups of flour for every 18 cups of water. To find out how many cups of flour are used for every cup of water, we divide the number of cups of flour by the number of cups of water.
23 cups of flour ÷ 18 cups of water = 1 5/18 or approximately 1.28 cups of flour per cup of water.
The correct statement that matches this calculation is none of the choices provided by the student. The proportion would be 1 5/18 cups of flour per cup of water, not 316 cups or 3 16 cups as stated in the options.
