James walks 1/5 of a mile to the bus stop in the morning. He walks 3/6 of a mile to his grandma's house in the afternoon. James said he walks a total of 2/4 of a mile in the morning and afternoon. Is James right or wrong? Show your work and explain your answer using complete sentences.
James is incorrect. If you add 1/5 and 3/6 you get 7/10 which is more than 1/2. 2/4 is equivalent to 1/2 so the answer 2/4 is not reasonable.
