You need to find the scale by taking the same side of each polygon. I marked which sides you should take from each example.

Scale factor is defined as the proportion of the one side to another. In our case: smaller side/ bigger side

1) scale factor k=9/12=3/4, which means that smaller figure is a 1/4 fourth smaller than the bigger one

2) k = 12/15= 4/5, which means that smaller figure is one fifth smaller than the bigger one

3) k =10/25= 2/5, so the bigger figure is 3/5 smaller from the bigger one

4) k= 8/16, which means that the smaller figure is a half of the bigger one

7 0

Answer: 1. I forgot how you write it but it adds 1/3 of the number, so for example 9/3 is 3, so you add 3 to 9 = 12 and then 21/3 is 7 and so you add 7 to 21 = 28. I forgot how you would write this but I know the answer is not 1/3 though because then that would be dilating. (srry this one isn't clear)

Also sorry I couldn't really help more I'm not very good at this stuff.

Step-by-step explanation:

40mins = 2/3 hour

the bus travelled (2/3 x 40) miles = 80/3 miles
