Understanding Fractions in an Unusual Pet Store

The video tutorial explores a problem involving an unusual pet store with cats, dogs, and bears. The task is to determine if the fraction of bears is greater than, less than, or equal to one-third of the total animals. Through visual and analytical methods, it is concluded that the fraction of bears is less than one-third, as having all animal fractions greater than one-third is impossible.

What makes the pet store unusual?

• It only has cats and dogs.

• It has more cats than dogs.

• It has an equal number of each animal.

• It includes bears as pets.

Which variable represents the number of dogs in the pet store?

• c

• b

• d

• a

What is the main question posed in the problem statement?

• Whether the fraction of bears is greater than, less than, or equal to one-third.

• Whether the sum of all animals is greater than one-third.

• Whether the number of dogs is greater than the number of bears.

• Whether the number of cats is greater than the number of dogs.

In the visual reasoning section, what happens if the fraction of bears is greater than one-third?

• The fraction of cats must be less than one-third.

• The fraction of dogs must be less than one-third.

• All fractions add up to more than a whole.

• The fraction of bears is equal to one-third.

Why can't the fraction of bears be equal to one-third?

• Because the fraction of dogs must be greater than one-third.

• Because the fraction of bears must be less than one-third.

• Because the fraction of dogs would then be less than one-third.

• Because the fraction of cats would be greater than one-third.
