The following are true of a scale factor:
It takes three cups of flour to bake a cake. How many cups of flour will it take to make seven cakes?
7 x 3 = 21
Seven is the scale factor. It increases the quantity of three cups of flour by a factor of seven.
I used 21 cups of flour to make seven identical cakes. How many cups of flour did I use for each cake?
21 ÷ 7 = 3
This is a division problem where the seven represents the divisor.
