    Answer:

    Scale factor of \frac{1}{7}.

    Step-by-step explanation:

    scale = \frac{scaled length}{actual length}

    The rectangle has been scaled by a factor of seven implies that its real dimensions has been multiplied by seven. Therefore, to scale the copy back to its original size, its dimension should be multiplied by a scale factor of \frac{1}{7}.

    Example:

    when the scale is 7;

    2 x 7 = 14

    3 x 7 = 21

    when the scale is \frac{1}{7};

    14 x \frac{1}{7} = 2

    21 x \frac{1}{7} = 3
