To find the solution to this expression, we need to perform the operations one by one following the order of operations (PEMDAS).

6 + 1/2 - 1 1/3 + 7 3/5 - 1 7/8 + 4 8/9

Step 1: 1/2 - 1 1/3 can be simplified by converting the mixed number into an improper fraction
1/2 - 4/
= 3/6 - 4/
= (3 - 8)/
= -5/6

Step 2: 7 3/5 - 1 7/8 can be simplified by converting the mixed number into an improper fraction
7 3/5 - 15/
= 35/5 + 3/5 - 15/
= 38/5 - 15/
To find a common denominator, we multiply the denominators together: 5 8 = 4
= (38 8 - 15 * 5) / 4
= (304 - 75) / 4
= 229/40

Step 3: Finally, add all the results obtained together
6 + (-5/6) + 229/40 + 4 8/
= 36/6 - 5/6 + 229/40 + 44/
= (36 - 5 + 69 + 240) / 4
= 340/4
= 17/
= 8.5

Therefore, the solution to the expression is 8.5.
