Question

9 км 040 м - 3 км 405 м = 5 ц : 5 кг = 1 т : 250 кг = 6 кг 400 г + 2 кг 800 г = 1 кг 400 г - 895 г = 2 ч - 47 мин =

Answer 1

9 км 040 м - 3 км 405 м = 5 км 635м

5 ц : 5 кг = 500÷5=100кг= 1ц

1 т : 250 кг = 1000кг÷250кг=4 кг

6 кг 400 г + 2 кг 800 г =9 кг 200гр

1 кг 400 г - 895 г = 1400 г-895 г=505 гр

2 ч - 47 мин =2×60-47=73 мин= 1 ч 13 мин

Answer 2

Let's solve each equation step by step:

1. 9 km 040 m - 3 km 405 m: To subtract these distances, we'll align the decimals (meters) and then subtract: 9 km 040 m

• 3 km 405 m

  ---

  5 km 635 m

  So, 9 km 040 m - 3 km 405 m = 5 km 635 m.

2. 5 ц : 5 кг: "ц" stands for centner, and "кг" stands for kilograms. A centner is equal to 100 kg. So, 5 ц is equal to 5 * 100 kg = 500 kg. Now, to find 5 ц : 5 кг, we divide 500 kg by 5 kg: 500 kg / 5 kg = 100.

   Therefore, 5 ц : 5 кг = 100.

3. 1 т : 250 кг: "т" stands for ton, and 1 ton is equal to 1000 kg. So, 1 т is equal to 1 * 1000 kg = 1000 kg. Now, to find 1 т : 250 кг, we divide 1000 kg by 250 kg: 1000 kg / 250 kg = 4.

   Therefore, 1 т : 250 кг = 4.

4. 6 кг 400 г + 2 кг 800 г: To add these weights, we add the kilograms and grams separately: 6 kg + 2 kg = 8 kg 400 g + 800 g = 1200 g

   Since there are 1000 grams in 1 kilogram, we can convert 1200 g to kilograms by dividing by 1000: 1200 g / 1000 = 1.2 kg

   Now, adding 8 kg and 1.2 kg: 8 kg + 1.2 kg = 9.2 kg

   Therefore, 6 кг 400 г + 2 кг 800 г = 9 кг 200 г.

5. 1 кг 400 г - 895 г: To subtract these weights, we'll align the decimals (grams) and then subtract: 1 kg 400 g

• 895 g

  ---

  505 g

  So, 1 кг 400 г - 895 г = 505 г.

6. 2 ч - 47 мин: To subtract these times, we need to ensure that both are in the same unit, either hours or minutes. Let's convert 2 hours to minutes: 2 hours * 60 minutes/hour = 120 minutes

   Now, we can subtract 47 minutes from 120 minutes: 120 minutes - 47 minutes = 73 minutes

   Therefore, 2 ч - 47 мин = 73 мин.
