Question

square b is a scaled copy of square a.
square a has side length 6, square b has side length 3.
what scale factor takes square a to square b?

Explanation:

Step1: Identify corresponding side lengths

Side length of Square A: $6$; Side length of Square B: $3$

Step2: Calculate scale factor

Scale factor = $\frac{\text{Side length of B}}{\text{Side length of A}}$
$\text{Scale factor} = \frac{3}{6} = \frac{1}{2}$

Answer:

$\frac{1}{2}$
