• I am still unsure about the scale factor... Could you please explain it in a simpler way please? My brain is not functioning today. (¬_¬")
• Is that the whole video what is the right answer
• im so confused its crazy. i have a test tommorrow about it
• In the last practice theres no way to tell if you have to use whole numbers or fractions this is stupid.
• Actually, that is not true. You use fractions when you are scaling down, and whole numbers when scaling up.

Hope this helps!
