Answer 3

To solve this expression, we need to perform the operations step by step:

Step 1: Convert all the mixed numbers to improper fractions. Step 2: Perform the addition and subtraction operations.

Let's start with Step 1:

3 5/9 can be written as an improper fraction: (9 * 3 + 5) / 9 = 28/9 (-2 1/4) can be written as an improper fraction: (4 * -2 + 1) / 4 = -9/4 (4 5/6) can be written as an improper fraction: (6 * 4 + 5) / 6 = 29/6 5 2/3 can be written as an improper fraction: (3 * 5 + 2) / 3 = 17/3

Now, the expression becomes:

(28/9) + (-9/4) - (29/6) - (17/3)

Moving to Step 2:

To perform the addition and subtraction operations, we need to find a common denominator for all the fractions, which is 36.

(28/9) * (4/4) = 112/36 (-9/4) * (9/9) = -81/36 (29/6) * (6/6) = 174/36 (17/3) * (12/12) = 204/36

Now the expression becomes:

(112/36) + (-81/36) - (174/36) - (204/36)

Finally, combine the fractions:

= (112 - 81 - 174 - 204) / 36 = (-347) / 36

Since -347 is not divisible by 36, we leave the answer as an improper fraction:

= -347/36
