The image shows a worksheet focused on converting mixed numbers to improper fractions. Let's go through each step and solve the problems:

### **Step-by-Step Explanation**:

**1. General Rule**:
   - To convert a mixed number to an improper fraction:
     \[
     \text{Improper Fraction} = \left(\text{Whole Number} \times \text{Denominator}\right) + \text{Numerator}
     \]
     The result becomes the numerator of the improper fraction, while the denominator remains the same.

---

**a) Convert \( 3 \frac{2}{3} \) to an improper fraction**:

   - **Step 1**: Multiply the whole number by the denominator: \( 3 \times 3 = 9 \).
   - **Step 2**: Add the numerator to this product: \( 9 + 2 = 11 \).
   - **Step 3**: Place the result over the original denominator: \( \frac{11}{3} \).

   **Result**: \( 3 \frac{2}{3} = \frac{11}{3} \)

---

**b) Convert \( 2 \frac{5}{6} \) to an improper fraction**:

   - **Step 1**: Multiply the whole number by the denominator: \( 2 \times 6 = 12 \).
   - **Step 2**: Add the numerator: \( 12 + 5 = 17 \).
   - **Step 3**: Place the result over the original denominator: \( \frac{17}{6} \).

   **Result**: \( 2 \frac{5}{6} = \frac{17}{6} \)

---

**c) Convert \( 7 \frac{1}{4} \) to an improper fraction**:

   - **Step 1**: Multiply the whole number by the denominator: \( 7 \times 4 = 28 \).
   - **Step 2**: Add the numerator: \( 28 + 1 = 29 \).
   - **Step 3**: Place the result over the original denominator: \( \frac{29}{4} \).

   **Result**: \( 7 \frac{1}{4} = \frac{29}{4} \)

---

**d) Convert \( 2 \frac{1}{2} \) to an improper fraction**:

   - **Step 1**: Multiply the whole number by the denominator: \( 2 \times 2 = 4 \).
   - **Step 2**: Add the numerator: \( 4 + 1 = 5 \).
   - **Step 3**: Place the result over the original denominator: \( \frac{5}{2} \).

   **Result**: \( 2 \frac{1}{2} = \frac{5}{2} \)

---

### **Summary of Answers**:
- \( 3 \frac{2}{3} = \frac{11}{3} \)
- \( 2 \frac{5}{6} = \frac{17}{6} \)
- \( 7 \frac{1}{4} = \frac{29}{4} \)
- \( 2 \frac{1}{2} = \frac{5}{2} \)
