Answer :
I saw the image. A larger octagon measuring 15 becomes a smaller octagon measuring 9.
15 ⇒ 9
larger measure * scale factor = smaller measure
let x be the scale factor:
15 * x = 9
x = 9/15
x = 3/5
The scale factor is 3/5.
15 ⇒ 9
larger measure * scale factor = smaller measure
let x be the scale factor:
15 * x = 9
x = 9/15
x = 3/5
The scale factor is 3/5.
