Sure, I'd be happy to help you solve these mathematical problems. Below are the solutions for each exercise you've provided: --- ### **First Set** 1. **\( 135.33 + 23.36 \)** \[ 135.33 + 23.36 = 158.69 \] 2. **\( 312.36 - 37.65 \)** \[ 312.36 - 37.65 = 274.71 \] 3. **\( 144.31 \times 3.5 \)** \[ 144.31 \times 3.5 = 505.09 \] 4. **\( 327.6 + 5.2 \)** \[ 327.6 + 5.2 = 332.8 \] --- ### **Exercise 10** 1. **\( 134.13 + 23.36 \)** \[ 134.13 + 23.36 = 157.49 \] 2. **\( 310.26 - 37.65 \)** \[ 310.26 - 37.65 = 272.61 \] 3. **\( 144.71 \times 3.5 \)** \[ 144.71 \times 3.5 = 506.49 \] 4. **\( 353.6 + 5.2 \)** \[ 353.6 + 5.2 = 358.8 \] --- ### **Exercise 11** 1. **\( 534.13 + 23.36 \)** \[ 534.13 + 23.36 = 557.49 \] 2. **\( 410.26 - 37.65 \)** \[ 410.26 - 37.65 = 372.61 \] 3. **\( 544.71 \times 3.5 \)** \[ 544.71 \times 3.5 = 1906.49 \] 4. **\( 464.36 + 5.2 \)** \[ 464.36 + 5.2 = 469.56 \] --- ### **Exercise 12** It seems like the problems for Exercise 12 are incomplete or missing. If you provide them, I'd be glad to assist you further! --- **Summary of Solutions:** | **Exercise** | **Problem** | **Solution** | |--------------|-------------------------|--------------| | **First Set** | \(135.33 + 23.36\) | 158.69 | | | \(312.36 - 37.65\) | 274.71 | | | \(144.31 \times 3.5\) | 505.09 | | | \(327.6 + 5.2\) | 332.8 | | **EXER 10** | \(134.13 + 23.36\) | 157.49 | | | \(310.26 - 37.65\) | 272.61 | | | \(144.71 \times 3.5\) | 506.49 | | | \(353.6 + 5.2\) | 358.8 | | **EXER 11** | \(534.13 + 23.36\) | 557.49 | | | \(410.26 - 37.65\) | 372.61 | | | \(544.71 \times 3.5\) | 1906.49 | | | \(464.36 + 5.2\) | 469.56 | If you have any more problems or need further explanations, feel free to ask!
