Answer 2

2-3/4 + 1-1/3

First, let's convert the mixed numbers to improper fractions: 2-3/4 = 4*2 + 3 = 11/4 1-1/3 = 3*1 + 1 = 4/3

Now we can add the fractions: 11/4 + 4/3

To add these fractions, we need to find a common denominator, which is 12. Then we can rewrite the fractions with the common denominator: 11/4 = 33/12 4/3 = 16/12

Now we can add the fractions: 33/12 + 16/12 = 49/12

So, the sum of 2-3/4 and 1-1/3 is 49/12. This can also be expressed as a mixed number: 49/12 = 4-1/12

Therefore, the sum of 2-3/4 and 1-1/3 is 4-1/12.
