"Transformations - Dilations"
A dilated figure does changes in shape, size, and location because of the scale factor. When you zoom into a picture, the figure may get bigger or smaller. Zooming relates to dilations because the figure may change the size in the figure. If a figure undergoes a dilation with a scale factor of 1.5, the figure will get bigger since its greater than 1. If the scale factor is 0.5, then the figure will get smaller because the scale factor is less than 1. Dilations and translations are different because dilations is when you use the factor scale and the shape will either get bigger or smaller and translations is when the figure is the same but in a different location. Multiplying by 1/3 is the same as dividing by 3 because when you multiply 1/3 by a number, you need to divide by 3 after. For example, 6 multiply 1/3 is 6/3. Then when you divide you will get 2. You will get the same answer if you divide 6 by 3, which is equals to 2. Therefore, its the same.
