Answer:
5"
Step-by-step explanation:
You are copying a square of side 20 inches into a smaller version of it that is exactly 25% of the original size.
Notice that 25% can be written in fraction form as: [tex]\frac{25}{100} = \frac{1}{4}[/tex]
This gives us a clue about how to reduce the original dimension: "multiply it by [tex]\frac{1}{4}[/tex], which is the same as divide it by 4:
[tex]20" * \frac{1}{4} = \frac{20"}{4} = 5"[/tex]
