Answer 2

To solve the given expression, we'll follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's start step by step:

а) 8 кг 26 г × 50:

Step 1: Convert kg to g to have a consistent unit. 8 kg = 8,000 g

Step 2: Add the grams to the given 26 g: 8,000 g + 26 g = 8,026 g

Step 3: Multiply by 50: 8,026 g × 50 = 401,300 g

So, 8 kg 26 г × 50 = 401,300 г.

б) 16 км 700 м : 50 30 м 5 дм × 600:

Step 1: Convert km to meters to have a consistent unit. 16 km = 16,000 m

Step 2: Add the meters to the given 700 m: 16,000 m + 700 m = 16,700 m

Step 3: Convert dm to meters. 5 dm = 5 * 0.1 m = 0.5 m

Step 4: Convert the entire quantity to meters. 50 m + 30 m + 0.5 m = 80.5 m

Step 5: Divide: 16,700 m ÷ 80.5 m = 207.45341614906833

Step 6: Multiply by 600: 207.45341614906833 * 600 = 124.471049689441

So, 16 км 700 м : 50 м 30 м 5 дм × 600 = 124.47.

в) 57 т 600 кг : 90 2 ч 8 мин × 2012 ч 40 мин:

Step 1: Convert tons to kg to have a consistent unit. 57 т = 57 * 1000 кг = 57,000 кг

Step 2: Add the kg to the given 600 кг: 57,000 кг + 600 кг = 57,600 кг

Step 3: Convert 2 ч 8 мин to minutes. 2 ч = 2 * 60 мин = 120 мин

Step 4: Add the minutes to the given 8 мин: 120 мин + 8 мин = 128 мин

Step 5: Convert 2012 ч 40 мин to minutes. 2012 ч = 2012 * 60 мин = 120,720 мин

Step 6: Add the minutes to the given 40 мин: 120,720 мин + 40 мин = 120,760 мин

Step 7: Divide: 57,600 кг ÷ 120,760 мин = 0.4760171294269957

Step 8: Multiply by 0.4760171294269957 * 2012 ч 40 мин = 958.6072346625768

So, 57 т 600 кг : 90 2 ч 8 мин × 2012 ч 40 мин = 958.61.

г) 8 кг 26 г × 50 ÷ 16 км 700 м : 50 м 30 м 5 дм × 600 57 т 600 кг : 90 2 ч 8 мин × 2012 ч 40 мин : 20:

Let's substitute the values we found in previous calculations:

401,300 г × 600 ÷ 124.47 × 958.61 ÷ 20 ≈ 292,382.04.

So, the result is approximately 292,382.04.
