12 dogs were in a pet show. There were 17 pets in total at the show. How many were not dogs?

Let’s start by highlighting all the information that we were given. There were 12 dogs in the pet show, 17 pets in total at the pet show. This is all the information we were given. And what is the question that we’re trying to answer? We want to know how many of the pets were not dogs?

Let’s write an equation to figure out how many were not dogs. Our equation should be something like this. The number of dogs plus the number of other pets will equal the total number of pets in the show. From here, we plug in the information we know. We know that there were 12 dogs and 17 total pets.

How many were not dogs? How many other type of pets were entered into the show? The question here is 12 plus some number equals 17. And that number is five. 12 plus five equals 17. Five pets in the show were not dogs.
