Answer:
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)
