Help a girl out please and thank you.

Answer 1

Explanation:

As all are similar polygons , corresponding sides will be in proportion.

`1)(9)/(12) =(3)/(4)\\\\`

Scale factor = 3 : 4

`2)(12)/(15)=(4)/(5)\\\\`

Scale factor = 4 : 5

`3) (10)/(25)=(2)/(5)\\`

Scale factor = 2:5

4)

`(8)/(16)=(1)/(2)`

Scale factor = 1 : 2
