Idont understand it . equivalent ratios.

okay, so first you make them into fractions. I'll use the car one as an example.

Ford=40/5

Flat=34/4

Dodge=32/4

Honda=17/2

Now that they are in fractions, simplify.

Ford=8/1 or just 8

Flat=17/2

Dodge=8/1 or just 8

Honda=17/2

If you notice, Ford and Dodge have the same ratio, as do Flat and Honda. I don't know if the teacher only wants one ratio or both, it is whatever you have already learned.

Now the next one.

Peanut Butter=1/14

Macadamia Nut=3/36

Chocolate Chip=2/24

Oatmeal raisin=2/32

Simplify.

Peanut Butter=1/14

Macadamia Nut=1/12

Chocolate Chip=1/12

Oatmeal Raisin=1/16

As you can see, Macadamia Nut and Chocolate Chip both have equal ratios.

I cannot do the last one for you, but I hope my answers are beneficial for you.
