The two figures are similar polygons. Find the scale factor for the small polygon to the large polygon

The answer is D.
Explanation: if you take a look at the numbers, the larger polygon must be divided by the smaller. For example, on one of the sides of the larger polygon, the side is 6. But on the smaller one it’s 4. So the equation is 6/4 which then equals 1.5. Now because all the answer choices are fractions you would divide the top number by the bottom one to see which number comes out to 1.5. In that case, it would be D. 3/2=1.5.
