    Step-by-step explanation:

    Let d be Debbie's distance from the fulcrum. Then Denise's is (16.5 - d) ft.

    Torque is measured in (distance) (force). Here, that'd be (distance) (weight).

    Here:

    96d = 120 (16.5 - d), or 96d = 1980 - 120d

    Adding 120d to both sides yields:

    216d = 1980, so that d = 9 1/6 ft. This is how far Debbie sits from the fulcrum

    Denise sits (16 1/2 ft - 9 1/6 ft) from the fulcrum: This works out to 7 1/3 ft. Her being heavier requires that she sit closer to the fulcrum than Debbie.

    Debbie sits 9 1/6 ft from the fulcrum, and Denise 7 1/3 ft.
