    This is a proportion problem.

    Let's make her Length x and her height 1/3 x.

    1/3 x = 20 inches

    x = 6 2/3 inches

    Molly's height is 6 2/3 inches.

    Check it.

    6 2/3 x 3 = ? (change the mixed number to a fraction)

    20/3 x 3 = ? (multiply)

    60/3 = ? (divide)

    20 inches. Yes, it checks.
