Answer 2

To solve this problem, we need to perform arithmetic operations on mixed numbers. One way to do this is to convert all the mixed numbers into improper fractions, perform the operations, and then simplify the result back into a mixed number.

Let's start by converting the mixed numbers into improper fractions:

8 6/7 = (7 x 8 + 6)/7 = 62/7 5 5/7 = (7 x 5 + 5)/7 = 40/7 3 3/7 = (7 x 3 + 3)/7 = 24/7 1 2/7 = (7 x 1 + 2)/7 = 9/7

Now, we can substitute these values into the original expression and simplify:

8 6/7 - 5 5/7 + 3 3/7 + 1 2/7 = 62/7 - 40/7 + 24/7 + 9/7 = (62 - 40 + 24 + 9)/7 = 55/7

Finally, we can simplify the result into a mixed number:

55/7 = 7 6/7

Therefore, 8 6/7 - 5 5/7 + 3 3/7 + 1 2/7 = 7 6/7.
