Answer 2

To add the mixed numbers and fractions, you need to convert the mixed numbers into improper fractions. Then, you can add the fractions together and simplify if needed. Let's go through each calculation:

1. 1 5/12 + 2 11/12: To convert the mixed numbers to improper fractions: 1 5/12 = (1 * 12 + 5)/12 = 17/12 2 11/12 = (2 * 12 + 11)/12 = 35/12

Now, add the fractions: 17/12 + 35/12 = (17 + 35)/12 = 52/12

The sum is 52/12. To simplify, we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 4: 52/12 = (52/4)/(12/4) = 13/3

Therefore, 1 5/12 + 2 11/12 = 13/3.

2. 3 7/13 + 2 7/13: To convert the mixed numbers to improper fractions: 3 7/13 = (3 * 13 + 7)/13 = 46/13 2 7/13 = (2 * 13 + 7)/13 = 33/13

Now, add the fractions: 46/13 + 33/13 = (46 + 33)/13 = 79/13

Therefore, 3 7/13 + 2 7/13 = 79/13.

3. 4 4/15 + 7 13/15: To convert the mixed numbers to improper fractions: 4 4/15 = (4 * 15 + 4)/15 = 64/15 7 13/15 = (7 * 15 + 13)/15 = 118/15

Now, add the fractions: 64/15 + 118/15 = (64 + 118)/15 = 182/15

Therefore, 4 4/15 + 7 13/15 = 182/15.

Final results: 1 5/12 + 2 11/12 = 13/3 3 7/13 + 2 7/13 = 79/13 4 4/15 + 7 13/15 = 182/15
