(iv)`15xx6xx(1)/(10)`
(v)`3xx4xx(1)/(16)xx15`
(vi)`20xx10xx(1)/(500)`

Answer

Let's solve each part step by step.

### (i) \(2 \times 4 \times 5\)

1. **Multiply the first two numbers**:
\[ 2 \times 4 = 8 \]
2. **Now multiply the result by the third number**:
\[ 8 \times 5 = 40 \]

**Final Answer**: \(40\)

### (ii) \(9 \times 3 \times 4\)

1. **Multiply the first two numbers**:
\[ 9 \times 3 = 27 \]
2. **Now multiply the result by the third number**:
\[ 27 \times 4 = 108 \]

**Final Answer**: \(108\)

### (iii) \(6 \times \frac{1}{5} \times 125\)

1. **Multiply \(6\) by \(\frac{1}{5}\)**:
\[ 6 \times \frac{1}{5} = \frac{6}{5} \]
2. **Now multiply the result by \(125\)**:
\[ \frac{6}{5} \times 125 = \frac{6 \times 125}{5} = \frac{750}{5} = 150 \]

**Final Answer**: \(150\)

---

### (iv) \(15 \times 6 \times \frac{1}{10}\)

1. **Multiply \(15\) by \(6\)**:
\[ 15 \times 6 = 90 \]
2. **Now multiply the result by \(\frac{1}{10}\)**:
\[ 90 \times \frac{1}{10} = 9 \]

**Final Answer**: \(9\)

---

### (v) \(3 \times 4 \times \frac{1}{16} \times 15\)

1. **Multiply \(3\) by \(4\)**:
\[ 3 \times 4 = 12 \]
2. **Now multiply the result by \(\frac{1}{16}\)**:
\[ 12 \times \frac{1}{16} = \frac{12}{16} = \frac{3}{4} \]
3. **Finally, multiply by \(15\)**:
\[ \frac{3}{4} \times 15 = \frac{45}{4} = 11.25 \]

**Final Answer**: \(11.25\)

---

### (vi) \(20 \times 10 \times \frac{1}{500}\)

1. **Multiply \(20\) by \(10\)**:
\[ 20 \times 10 = 200 \]
2. **Now multiply the result by \(\frac{1}{500}\)**:
\[ 200 \times \frac{1}{500} = \frac{200}{500} = \frac{2}{5} = 0.4 \]

**Final Answer**: \(0.4\)
