What is 1 1/4 + (3 2/3 +5 3/4)?

Step-by-step explanation:

Because this whole problem focuses on the addition of mixed numbers, we can drop the parentheses right now without affecting the problem solution.

The two denominators shown are 4 and 3; the LCD is therefore 12.

Rewriting the problem, we get:

1 3/12 + 3 8/12 + 5 9/12, or

                  3 + 8 + 9

1 + 3 + 5 +

                         12

This simplifies to 9 20/12, or 10 8/12, or 10 2/3 (answer)
