Answer 3

To solve the expression:

(9/22 - 4/9) / (3 - 1) + 8/15 + 8/11

Let's break it down step by step:

1. First, calculate the expression inside the first set of parentheses:

(9/22 - 4/9) = (81/198 - 88/198)

To subtract fractions, you need a common denominator, which in this case is 198:

(81/198 - 88/198) = (-7/198)

2. Now, move to the second set of parentheses:

(3 - 1) = 2

3. Combine the results from step 1 and step 2:

(-7/198) / 2

To divide by 2, you can simply divide the numerator by 2:

(-7/198) / 2 = (-7/198) * (1/2) = (-7/396)

4. Finally, add the last two fractions:

8/15 + 8/11

To add these fractions, you need a common denominator, which in this case is 165:

(8/15 * 11/11) + (8/11 * 15/15) = (88/165 + 120/165)

Now, add the fractions:

(88/165 + 120/165) = (208/165)

5. Now, add the results from step 4 and step 3:

(-7/396) + (208/165)

To add these fractions, you need a common denominator, which is the least common multiple of 396 and 165, which is 65340:

(-7/396) * (165/165) + (208/165) * (396/396) = (-1155/65340) + (82528/65340)

Now, add the fractions:

(-1155/65340 + 82528/65340) = (81373/65340)

So, the final result of the expression is 81373/65340.
