Please I need help on this and I have no notes to go off of: Fill in the blank
Two ratios set equal to each other make a proportion so long as their 1) products equal the same value. When you set -up proportions it is very critical/important that you pay attention to the 2) on the values. Paying attentions to the labels allows you to set -up the values in a consistent manner. You are making a relationship statement that says one ratio is the same as the other (equivalent); it is also a comparison of the units. For example, feet per second, miles per hour, dollars per hour, cost for each; these are called 3) (s) because the denominator label is for a unit of one. Scale drawings incorporate the ratio as a factor---called the 4) factor. This ratio determines if the original image is 5) or shrunk. If the Scale Factor is --

6) than 1 ; the original image is shrunk; Conversely, if the SF is >1, then the image is 7)by that ratio. This is like when they dilate you pupils or when you hit the + symbol on the cell phone or computer screen.
