- Ones Block: 4
- Total: \( 2 \times 100 + 3 \times 10 + 4 \times 1 = 200 + 30 + 4 = 234 \)

#### 2)
- Hundreds Block: 1
- Tens Block: 6
- Ones Block: 5
- Total: \( 1 \times 100 + 6 \times 10 + 5 \times 1 = 100 + 60 + 5 = 165 \)

#### 3)
- Hundreds Block: 1
- Tens Block: 4
- Ones Block: 7
- Total: \( 1 \times 100 + 4 \times 10 + 7 \times 1 = 100 + 40 + 7 = 147 \)

#### 4)
- Hundreds Block: 3
- Tens Block: 0
- Ones Block: 9
- Total: \( 3 \times 100 + 0 \times 10 + 9 \times 1 = 300 + 0 + 9 = 309 \)
