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.
