    Ratio

    Hi in one of my books there is a wall kind of diagram with a double sided arrow and in the middle is 80 m. If i use a ruler How do i know to go by millimeters or centimeters

    The diagram shows the face of a wall drawn to scale. What scale has been used?

    A) 1:8 (B) 1:80 C)1:800 (D) 1:8000

    Re: Ratio

    Determine the length of the diagram in centimeters. Determine the length of the real wall in centimeters (i.e., convert 80 meters to centimeters). Divide the former by the latter.
