Answer 3

To simplify the expression, you can follow these steps:

Step 1: Convert mixed numbers to improper fractions. Step 2: Perform addition and subtraction of fractions. Step 3: Combine any whole numbers separately.

Let's break it down:

1. Convert mixed numbers to improper fractions:

• 6 5/9 = 59/9
• 1 5/18 = 23/18
• -4 7/18 = -151/18
• 2/9 (remains the same)
• 2 8/9 = 26/9

2. Perform addition and subtraction of fractions:

(59/9) - (23/18) - (-151/18) + (2/9) - (26/9)

3. Combine any whole numbers separately:

6 - 1 + 2 = 7

Now, we have:

(59/9) - (23/18) - (-151/18) + (2/9) - (26/9)

4. Now, we can combine the fractions:

(59/9) - (23/18) + (151/18) + (2/9) - (26/9)

5. Find a common denominator for the fractions, which is 18:

[(259)/18] - (23/18) + (151/18) + [(22)/18] - [(2*26)/18]

6. Perform the arithmetic operations:

(118/18) - (23/18) + (151/18) + (4/18) - (52/18)

7. Combine the fractions:

(118 - 23 + 151 + 4 - 52)/18

8. Perform the remaining arithmetic:

(198/18)/18

9. Simplify the fraction:

(11/1)/18 = 11/18

So, the simplified result of the expression is 11/18.
