А) 8 кг 26 г× 50 16 км 700 м: 50 30 м 5 дм ×600 57 т 600 кг : 90 2 ч8 мин ×20 12 ч 40 мин : 20 ​

Answer 1

Ответ:

Пошаговое объяснение:

8 кг 26 г× 50=401 кг 300 г

16 км 700 м: 50=334 м

30 м 5 дм ×600=188000 м

57 т 600 кг : 90 = 640 кг

2 ч8 мин ×20=42 ч 40 мин

12 ч 40 мин : 20 ​= 38 мин

Answer 2

To simplify the given expression, let's take it step by step:

А) 8 кг 26 г × 50:

Step 1: Convert 8 kg to grams: 8 kg = 8000 g Step 2: Add 26 g: 8000 g + 26 g = 8026 g Step 3: Multiply by 50: 8026 g × 50 = 401,300 g

So, 8 kg 26 g × 50 = 401,300 g.

B) 16 км 700 м ÷ 50 м 5 дм:

Step 1: Convert 16 km to meters: 16 km = 16,000 m Step 2: Add 700 m: 16,000 m + 700 m = 16,700 m Step 3: Convert 50 m to decimeters: 50 m = 500 dm Step 4: Add 5 dm: 500 dm + 5 dm = 505 dm Step 5: Divide: 16,700 m ÷ 505 dm = 33

So, 16 км 700 м ÷ 50 м 5 дм = 33.

C) 600 м 57 т 600 кг ÷ 90:

Step 1: Convert 57 tons to kilograms: 57 tons = 57,000 kg Step 2: Add 600 kg: 57,000 kg + 600 kg = 57,600 kg Step 3: Divide: 57,600 kg ÷ 90 = 640

So, 600 м 57 т 600 кг ÷ 90 = 640.

D) 2 ч 8 мин × 20:

Step 1: Convert 2 hours to minutes: 2 hours = 2 × 60 = 120 minutes Step 2: Add 8 minutes: 120 minutes + 8 minutes = 128 minutes Step 3: Multiply by 20: 128 minutes × 20 = 2560 minutes

So, 2 ч 8 мин × 20 = 2560 minutes.

E) 12 ч 40 мин : 20:

Step 1: Convert 12 hours to minutes: 12 hours = 12 × 60 = 720 minutes Step 2: Add 40 minutes: 720 minutes + 40 minutes = 760 minutes Step 3: Divide: 760 minutes ÷ 20 = 38

So, 12 ч 40 мин : 20 = 38.

Now, the final expression becomes:

401,300 g × 33 × 640 × 2560 × 38.

To calculate the result, simply multiply the numbers together:

401,300 g × 33 × 640 × 2560 × 38 = 12,362,419,200,000 g.

Note: The final answer is given in grams (g).
