Question

the rectangles below are scaled copies of one another. the side that corresponds to 20 units in the original rectangle is 5 units in the scaled copy. start by finding the scale factor from the original rectangle to the scaled copy. original rectangle a blue rectangle with length labeled 20 and height labeled 12 scaled copy a smaller blue rectangle with length labeled 5 the scale factor is...

Explanation:

Step1: Identify corresponding sides

The original rectangle has a side of 20 units, and the scaled copy has the corresponding side of 5 units.

Step2: Calculate scale factor

The scale factor from the original to the scaled copy is the length of the scaled side divided by the length of the original side. So, scale factor $= \frac{5}{20}$.

Step3: Simplify the fraction

Simplify $\frac{5}{20}$ by dividing both the numerator and the denominator by 5. $\frac{5\div5}{20\div5} = \frac{1}{4}$.

Answer:

$\frac{1}{4}$
