    5/14 is the answer. I'll do my best bud

    Answer↑

    Steps↓

    Convert 2 1/2 to an improper fraction:

    2 + 2 + 1 over 2

    Once you add the numbers, that will be 5/2.

    Now, multiply that with 1/7:

    5/2 • 1/7

    Your answer will be 5/14

    Therefore, Rock A weighs 5/14 pounds
