Answer : There are roughly 4 - 5 birds at the pet store

Step - by - step explanation :

Since there are 48 dogs, and 39 cats . . . in - order to find out how many birds there are we need to do . . .

48 + 39 = 87 <-- This is the total of cats and dogs combined

Now, because we know the remainder of animals at the store is birds we do . . .

99 <-- The total number of pets at the store - 87 = 12

There are 12 birds at the store

To find the remainder . . .

40/40 - 26/40 = 14/40 <-- The remaining amount of animals

I forgot how I got this but there are roughly 4 - 5 birds at the pet store
