Question

2. If you brought your dog to a dog park and wanted to count the total number ofdogs present, which of the following sets of numbers would best describe youranswer?a. Irrationalb. Rationalc. Integerd. Natural

Answer 1

Let's first think about the object that we are counting: dogs.

Dogs cannot be counted in fractions.

Since you cannot have 1/2 dog or 4/5 dogs, then we should forget about the rational and irrational numbers.

Also, we cannot have -1 dogs or any negative number of dogs (or at least if you owe someone a dog but this is not the case), therefore, the correct set would be the Natural set of numbers
