Answer 1

Ответ:

Пошаговое объяснение:

1) 1 kg 200 g + 2 kg 400 g  = 3 kg 600 g

2) 2 kg 300 g + 3 kg 600 g = 5 kg 900 g

3) 3 kg 400 g + 4 kg 300 g = 7 kg 700 g

4) 5 kg 300 g + 7 kg 600 g = 12 kg 900 g

Answer 2

Let's solve the given addition problems:

1. 1 kg 200 g + 2 kg 400 g: To add the weights, we add the kilograms and the grams separately: Kilograms: 1 kg + 2 kg = 3 kg Grams: 200 g + 400 g = 600 g

   Therefore, 1 kg 200 g + 2 kg 400 g = 3 kg 600 g.

2. 2 kg 300 g + 3 kg 600 g: Kilograms: 2 kg + 3 kg = 5 kg Grams: 300 g + 600 g = 900 g

   Therefore, 2 kg 300 g + 3 kg 600 g = 5 kg 900 g.

3. 3 kg 400 g + 4 kg 300 g: Kilograms: 3 kg + 4 kg = 7 kg Grams: 400 g + 300 g = 700 g

   Therefore, 3 kg 400 g + 4 kg 300 g = 7 kg 700 g.

4. 5 kg 300 g + 7 kg 600 g: Kilograms: 5 kg + 7 kg = 12 kg Grams: 300 g + 600 g = 900 g

   Since 900 g is equal to 1 kg 900 g, we can carry over the excess grams to the kilograms: Kilograms: 12 kg + 1 kg = 13 kg Grams: 900 g - 1000 g = -100 g (Negative grams indicate a reduction of 1 kg)

   Therefore, 5 kg 300 g + 7 kg 600 g = 13 kg 100 g.

Final results:

1. 1 kg 200 g + 2 kg 400 g = 3 kg 600 g
2. 2 kg 300 g + 3 kg 600 g = 5 kg 900 g
3. 3 kg 400 g + 4 kg 300 g = 7 kg 700 g
4. 5 kg 300 g + 7 kg 600 g = 13 kg 100 g.
