Let's analyze and solve the given expression from the image:

The expression is:
\[
2 \frac{3}{11} + \frac{4}{9} \div 1 \frac{7}{15}
\]

To solve this, we can break it down into a series of steps:

### Step 1: Convert Mixed Numbers to Improper Fractions
1. \( 2 \frac{3}{11} \) becomes \( \frac{25}{11} \) (since \( 2 \times 11 + 3 = 25 \)).
2. \( 1 \frac{7}{15} \) becomes \( \frac{22}{15} \) (since \( 1 \times 15 + 7 = 22 \)).

The expression now looks like:
\[
\frac{25}{11} + \frac{4}{9} \div \frac{22}{15}
\]

### Step 2: Handle the Division
Division by a fraction is equivalent to multiplying by its reciprocal. So, we rewrite the division as multiplication:
\[
\frac{25}{11} + \frac{4}{9} \times \frac{15}{22}
\]

### Step 3: Perform the Multiplication
Now, multiply \( \frac{4}{9} \) by \( \frac{15}{22} \):
\[
\frac{4 \times 15}{9 \times 22} = \frac{60}{198}
\]

To simplify \( \frac{60}{198} \), we find the greatest common divisor of 60 and 198, which is 6. So,
\[
\frac{60}{198} = \frac{10}{33}
\]

Now the expression is:
\[
\frac{25}{11} + \frac{10}{33}
\]

### Step 4: Add the Fractions
To add \( \frac{25}{11} \) and \( \frac{10}{33} \), we need a common denominator. The least common multiple of 11 and 33 is 33.

1. Convert \( \frac{25}{11} \) to a fraction with denominator 33:
   \[
   \frac{25}{11} = \frac{75}{33}
   \]

2. Now add:
   \[
   \frac{75}{33} + \frac{10}{33} = \frac{85}{33}
   \]

### Step 5: Simplify the Result
The fraction \( \frac{85}{33} \) is already in its simplest form, but it can be expressed as a mixed number:
\[
\frac{85}{33} = 2 \frac{19}{33}
\]

### Final Answer
The result of the expression is:
\[
2 \frac{19}{33}
\]
