Step-by-Step Solution

To solve this problem, we'll perform operations involving both fractions and whole numbers:

  • Step 1: Combine the fractional parts 49-\frac{4}{9} and 59\frac{5}{9}.

  • Step 2: Add the remaining whole numbers 55 and 2-2.

  • Step 3: Sum the results from Step 1 and Step 2.

Let's start:
Step 1: Work with the fractions together. - We have 49-\frac{4}{9} and 59\frac{5}{9}, both have the same denominator, thus can be directly added: 49+59=4+59=19 -\frac{4}{9} + \frac{5}{9} = \frac{-4+5}{9} = \frac{1}{9}

Step 2: Add the integer components 55 and 2-2: 5+(2)=52=3. 5 + (-2) = 5 - 2 = 3.

Step 3: Combine results from Step 1 and Step 2: 3+19=279+19=289 3+\frac{1}{9}=\frac{27}{9}+\frac{1}{9}=\frac{28}{9} .

Therefore, the final result of the expression is 289\frac{28}{9}.

Answer

289 \frac{28}{9}
