Barbara ran 2/8 of a mile before lunch and 3/12 of a mile after lunch. How far did she run in all? Explain how you got that answer.

Answer 1

To find the total distance that Barbara ran, we need to add the distances she ran before and after lunch.

Before lunch, Barbara ran 2/8 of a mile. Since the denominator is the same for both fractions (8), we can add the numerators: 2 + 3 = 5.

After lunch, Barbara ran 3/12 of a mile. Since the denominator is the same for both fractions (12), we can add the numerators: 5 + 3 = 8.

Therefore, Barbara ran a total of 8/8 of a mile. Since 8/8 is equal to 1, we can conclude that Barbara ran 1 mile in total.
