Answer: Choice A) 10/27 cup flour
=======================================================
Work Shown:
3/5 cup water = 2/3 cup flour
15*(3/5) cup water = 15*(2/3) cup flour
9 cups water = 10 cups flour
9/27 cup water = 10/27 cup flour
1/3 cup water = 10/27 cup flour
In the second step I multiplied both sides by 15 to clear out the fractions. In the second to last step, I divided both sides by 27 so that it forms the fraction 9/27 which reduces to 1/3.
