Scale : The relationship between the measurements on drawing object and the measurements of a real object is called scale of the drawing.
Scale Drawing : A drawing that is used to represent an object that is too large or too small in to be drawn at actual size. So, to draw or represent these these type of objects we use a scale factor and the associated drawing is called Scale Drawing.
Hence, A drawing that is a smaller representation of a real object is called a Scale Drawing.
<u><em>A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (called the scale). The scale is shown as the length in the drawing, then a colon (":"), then the matching length on the real thing.</em></u>
The greatest common factor between 8 and 2 is 2. So 2 will go into 8, 4 times. And 2 will go into 2, 1 time. So simplified the equivalent ratio is 4:1.
