    8/3 = 1/x or x = 3/8

    Step-by-step explanation:

    Set up the ratio

    (2/3) / (1/4) = 1/x

    solve for x

    8/3 = 1/x or x = 3/8

    Wax required for entire car = 3/8 bottle of wax

    Step-by-step explanation:

    We have given,

    1/4 bottle of car wax can wax 2/3 of her car.

    We need to find the wax required to wax her car completely.

    Let's derive the relation between wax bottle and car waxing rate:

    2/3 of car waxing needs 1/4 of bottle of wax.

    for entire car waxing, i. e 1 car waxing needs (1/4) / (2/3) bottle of wax

    wax required for entire car = (1/4) * (3/2)

    =3/8 bottle of wax
