    Answer: 10 pounds

    Step-by-step explanation:

    We can solve this using proportion

    2 1/2 pounds = 1/4 cups

    x = 1 cups

    we change 2 1/2 to improper fractions = > 5/2

    5/2 pounds = 1/4 cups

    x = 1 cups

    cross multiply

    5/2 = 1/4 x

    5/2 = x / 4

    cross multiply

    2x = 20

    Divide bothside by 2

    2x/2 = 20/2

    x = 10

    Therefore 10 pounds of flour is use for 1 cup
