Answer 2

To solve the expression, we need to perform the subtraction between the two mixed numbers: 3 11/12 and -4 4/9.

Step 1: Convert the mixed numbers into improper fractions: 3 11/12 = (3 * 12 + 11)/12 = 35/12 -4 4/9 = (-4 * 9 + 4)/9 = -40/9

Step 2: Now, subtract the two fractions: 35/12 - (-40/9)

Step 3: To subtract fractions, we need a common denominator. The least common multiple (LCM) of 12 and 9 is 36.

Step 4: Convert both fractions to have a denominator of 36: (35/12) * (3/3) = 105/36 (-40/9) * (4/4) = 160/36

Step 5: Now, subtract the fractions: 105/36 - 160/36

Step 6: Subtract the numerators and keep the common denominator: (105 - 160)/36 = -55/36

The result of the expression is -55/36. This can also be written as a mixed number: -1 19/36.
