Sure! Let's simplify each of the given expressions step by step.

### a) $$ 6\left(\frac{1}{2} + \frac{1}{3}\right) $$

1. **Add the fractions inside the parentheses:**
   $$
   \frac{1}{2} + \frac{1}{3} = \frac{3}{6} + \frac{2}{6} = \frac{5}{6}
   $$
2. **Multiply by 6:**
   $$
   6 \times \frac{5}{6} = 5
   $$

**Simplified Result:** $$ 5 $$

---

### b) $$ \frac{1}{2}(18 + 36) $$

1. **Add the numbers inside the parentheses:**
   $$
   18 + 36 = 54
   $$
2. **Multiply by $$\frac{1}{2}$$:**
   $$
   \frac{1}{2} \times 54 = 27
   $$

**Simplified Result:** $$ 27 $$

---

### c) $$ 12(13 - 8) - 11(22 - 17) $$

1. **Calculate inside each set of parentheses:**
   $$
   13 - 8 = 5 \quad \text{and} \quad 22 - 17 = 5
   $$
2. **Multiply and subtract:**
   $$
   12 \times 5 - 11 \times 5 = 60 - 55 = 5
   $$

**Simplified Result:** $$ 5 $$

---

### d) $$ 1.5 \times 3 + 1.5 \times 4 $$

1. **Factor out 1.5:**
   $$
   1.5 \times (3 + 4) = 1.5 \times 7 = 10.5
   $$

**Simplified Result:** $$ 10.5 $$

---

### e) $$ \frac{1}{8} \times 2 \times 8 $$

1. **Multiply the fractions and integers step by step:**
   $$
   \frac{1}{8} \times 2 = \frac{2}{8} = \frac{1}{4}
   $$
   $$
   \frac{1}{4} \times 8 = 2
   $$

**Simplified Result:** $$ 2 $$

---

### f) $$ \frac{3}{4} \times \frac{4}{3} \times 12 $$

1. **Multiply the fractions first:**
   $$
   \frac{3}{4} \times \frac{4}{3} = 1
   $$
2. **Multiply by 12:**
   $$
   1 \times 12 = 12
   $$

**Simplified Result:** $$ 12 $$

---

### Summary of Results

- **a)** $$ 5 $$
- **b)** $$ 27 $$
- **c)** $$ 5 $$
- **d)** $$ 10.5 $$
- **e)** $$ 2 $$
- **f)** $$ 12 $$
- **a)** 5 - **b)** 27 - **c)** 5 - **d)** 10.5 - **e)** 2 - **f)** 12
