What fraction of the animals in the store are birds and bunnies?

There are no animals in the store that are both birds and bunnies; so the answer is 0.

What fraction of the animals in the store are not birds and bunnies?

ALL of them are not both birds and bunnies; so the answer is 1.

Now let's ask and answer the right questions.

What fraction of the animals in the store are birds OR bunnies?

birds 2/5; bunnies 3/8. Get a common denominator: 5*8 = 40.

birds 16/40; bunnies 15/40

birds OR bunnies: 16/40+15/40 = 31/40

What fraction of the animals in the store are not birds OR bunnies?

1-31/40 = 9/40
