Calculate the value by following steps: - step0: Calculate: \(42+6+\left(3\times 5\right)-\left(\frac{22}{42}\right)-\left(\frac{12}{2}\right)\) - step1: Multiply the numbers: \(42+6+15-\left(\frac{22}{42}\right)-\left(\frac{12}{2}\right)\) - step2: Reduce the fraction: \(42+6+15-\frac{11}{21}-\left(\frac{12}{2}\right)\) - step3: Divide the terms: \(42+6+15-\frac{11}{21}-6\) - step4: Simplify: \(42+15-\frac{11}{21}\) - step5: Add the numbers: \(57-\frac{11}{21}\) - step6: Reduce fractions to a common denominator: \(\frac{57\times 21}{21}-\frac{11}{21}\) - step7: Transform the expression: \(\frac{57\times 21-11}{21}\) - step8: Multiply the numbers: \(\frac{1197-11}{21}\) - step9: Subtract the numbers: \(\frac{1186}{21}\) Calculate or simplify the expression \( 3*45+9 \). Calculate the value by following steps: - step0: Calculate: \(3\times 45+9\) - step1: Multiply the numbers: \(135+9\) - step2: Add the numbers: \(144\) Calculate or simplify the expression \( 3600+60-50 \). Calculate the value by following steps: - step0: Calculate: \(3600+60-50\) - step1: Calculate: \(3610\) Calculate or simplify the expression \( 5*(4800+400) \). Calculate the value by following steps: - step0: Calculate: \(5\left(4800+400\right)\) - step1: Add the numbers: \(5\times 5200\) - step2: Multiply the numbers: \(26000\) Here are the calculations for each expression: a) \( 5 \times (4800 + 400) = 5 \times 5200 = 26000 \) b) \( 6 \times 28 \div 4 = 168 \div 4 = 42 \) c) \( 3 \times 45 + 9 = 135 + 9 = 144 \) d) \( 42 + 6 + (3 \times 5) - \frac{22}{42} - \frac{12}{2} \) - First, calculate \( 3 \times 5 = 15 \) - Then, \( 42 + 6 + 15 = 63 \) - Now, calculate \( \frac{22}{42} \approx 0.5238 \) and \( \frac{12}{2} = 6 \) - Finally, \( 63 - 0.5238 - 6 \approx 56.4762 \) The result can be expressed as \( 56 \frac{10}{21} \) or approximately \( 56.4 \). e) \( 3600 + 60 - 50 = 3610 \) f) \( (300 + 10) + (40 \times 5) = 310 + 200 = 510 \) Here are the final results: - a) \( 26000 \) - b) \( 42 \) - c) \( 144 \) - d) \( 56 \frac{10}{21} \) (or approximately \( 56.4 \)) - e) \( 3610 \) - f) \( 510 \)
