Answer 2

To add these mixed numbers, you first need to convert them into improper fractions, then combine the fractions and whole numbers separately, and finally add the results.

Step 1: Convert mixed numbers to improper fractions (2 3/13) = (2 * 13 + 3) / 13 = 29 / 13 (1 1/13) = (1 * 13 + 1) / 13 = 14 / 13

Step 2: Add the fractions (29/13 - 7/13) + (14/13 + 3/13)

Step 3: Combine the fractions with the same denominators (29/13 - 7/13) = (29 - 7) / 13 = 22 / 13 (14/13 + 3/13) = (14 + 3) / 13 = 17 / 13

Step 4: Add the whole numbers 2 + 1 = 3

Step 5: Combine the results 3 + 22/13 + 17/13

Step 6: Combine the fractions and whole number 3 + (22 + 17) / 13 = 3 + 39 / 13

The final result is 3 + 39/13.
