Ms. Dennis ran on the treadmill for 1/2 an hour. Her brother, Aaron ran for 2/4 of an hour. Aaron says that he ran more than Ms. Dennis because he has a larger numerator and that means that he ran more. Is he correct or incorrect? Why or why not?
What is incorrect. He is incorrect because 1/2 and 2/4 are equivalent fractions. One-half is equal to two-fourths.
