Answer 3

Let's simplify the expression step by step:

Step 1: Convert mixed fractions to improper fractions. 2 9/11 can be written as (2 * 11 + 9) / 11 = 23/11 -3 7/22 can be written as (-3 * 22 + 7) / 22 = (-59) / 22

Step 2: Add the fractions. 23/11 + (-59/22)

Step 3: Find a common denominator for the fractions, which is 22 in this case. Multiply the numerator and denominator of the first fraction by 2 to make the denominators the same:

(23 * 2) / (11 * 2) + (-59/22)

Step 4: Perform the addition:

46/22 + (-59/22)

Step 5: Combine the fractions:

(46 - 59) / 22

Step 6: Complete the subtraction:

-13 / 22

So, the result of the expression is -13/22.
