In Mary’s homeroom, \(\frac{10}{28}\) of the students have a cat, \(\frac{6}{12}\) have a dog, and \(\frac{2}{14}\) have a pet bird. For numbers 11a–11c, select True or False for each statement.

a. In simplest form, \(\frac{5}{14}\) of the students have a cat.

b. In simplest form, \(\frac{2}{4}\) of the students have a dog.

c. In simplest form, \(\frac{1}{7}\) of the students have a pet bird.
