If 20 3rd graders owned birds, how many third graders were surveyed?

Reptiles 5%

Birds 5%

Fish 10%

Cats 35%

Dogs 45%

I did 5% of 30 = .05 x 30 = 1.5

30/1.5 = 20 third graders

BUT I am thinking I am doing something wrong? Where did I go wrong?

Should it be 30/.05 = 600 students were surveyed?

I want to understand my steps on where I messed up? Could you show me?
