Let's work on the questions from the image:

### 1) Simplifying Fractions:
   The following fractions need to be simplified.

   a) \( \frac{25}{35} \)
   - You divided both numerator and denominator by 5, simplifying to:
     \[
     \frac{25}{35} = \frac{5}{7}
     \]

   f) \( \frac{4 \times 5}{35} \)
   - Multiply the numerator: \( 4 \times 5 = 20 \), resulting in:
     \[
     \frac{20}{35} = \frac{4}{7}
     \]
     (You mistakenly wrote 9/7. The correct answer is \( \frac{4}{7} \)).

### 2) Solving the equation:
   \[
   \frac{3x + 5}{4} - \frac{2x - 3}{3} = 3
   \]
   To solve this, let's follow these steps:
   
   **Step 1:** Find a common denominator. The least common denominator (LCD) between 4 and 3 is 12.

   - Multiply the first term by 3/3 and the second term by 4/4:
     \[
     \frac{3(3x + 5)}{12} - \frac{4(2x - 3)}{12} = 3
     \]
     This simplifies to:
     \[
     \frac{9x + 15}{12} - \frac{8x - 12}{12} = 3
     \]

   **Step 2:** Combine the fractions:
     \[
     \frac{(9x + 15) - (8x - 12)}{12} = 3
     \]
     Simplify the numerator:
     \[
     \frac{9x + 15 - 8x + 12}{12} = 3
     \]
     \[
     \frac{x + 27}{12} = 3
     \]

   **Step 3:** Multiply both sides by 12 to eliminate the denominator:
     \[
     x + 27 = 36
     \]

   **Step 4:** Solve for \( x \):
     \[
     x = 36 - 27
     \]
     \[
     x = 9
     \]

The solution to the equation is \( x = 9 \).
