It appears that you've provided a series of mathematical expressions involving numbers and operations. To assist you, let’s simplify each expression step-by-step. I'll first rewrite them in a clearer format. 1. \( 3.3 \div 0.61 \times 7 \) 2. \( 2.2 \times 6.4 \times 0.15 \) 3. \( 1.6 \times 4.6 \times 0.03 \) 4. \( 2 + 20 \div 8.75 \) 5. \( 0.18 \div 1.5 + 2.88 \) Let's calculate each one. ### 1. \( 3.3 \div 0.61 \times 7 \) Calculating this step by step: - \( 3.3 \div 0.61 \approx 5.4098 \) - \( 5.4098 \times 7 \approx 37.8686 \) **Result: Approximately 37.87** --- ### 2. \( 2.2 \times 6.4 \times 0.15 \) Calculating this step by step: - \( 2.2 \times 6.4 = 14.08 \) - \( 14.08 \times 0.15 = 2.112 \) **Result: 2.112** --- ### 3. \( 1.6 \times 4.6 \times 0.03 \) Calculating this step by step: - \( 1.6 \times 4.6 = 7.36 \) - \( 7.36 \times 0.03 = 0.2208 \) **Result: 0.2208** --- ### 4. \( 2 + 20 \div 8.75 \) Calculating this step by step: - \( 20 \div 8.75 \approx 2.2857 \) - \( 2 + 2.2857 \approx 4.2857 \) **Result: Approximately 4.29** --- ### 5. \( 0.18 \div 1.5 + 2.88 \) Calculating this step by step: - \( 0.18 \div 1.5 \approx 0.12 \) - \( 0.12 + 2.88 = 3.00 \) **Result: 3.00** --- ### Summary of Results 1. \( 3.3 \div 0.61 \times 7 \) ≈ **37.87** 2. \( 2.2 \times 6.4 \times 0.15 \) = **2.112** 3. \( 1.6 \times 4.6 \times 0.03 \) = **0.2208** 4. \( 2 + 20 \div 8.75 \) ≈ **4.29** 5. \( 0.18 \div 1.5 + 2.88 \) = **3.00** If you have any specific questions or need further assistance, please let me know!
