Question

3 kg + 2 kg 400 g=5 kg - 3 kg 600 g=3 kg 800 g + 4 kg 300 g=8 kg 800 g - 5 kg 600 g=​

Answer 1

Пошаговое объяснение:

5kg 400g

1kg 400g

8 kg 100g

3 kg 200g

Поскольку в 1kg - 1000g :

3kg+2kg 400g=5 kg 400g;

5kg-3kg 600g=2kg-600g=1 kg 400g;

3kg 800g +4 kg 300g=7kg 800+300g=8kg 100g;

8kg 800g-5kg 600g=3kg 800g-600-=3kg 200g.

Answer 2

To solve these arithmetic equations involving kilograms and grams, we need to ensure that the units are consistent. Let's convert all the grams to kilograms and perform the calculations.

1. 3 kg + 2 kg 400 g: First, convert 2 kg 400 g to kilograms: 2 kg 400 g = 2 kg + (400 g / 1000) kg = 2.4 kg Now, perform the addition: 3 kg + 2.4 kg = 5.4 kg

2. 5 kg - 3 kg 600 g: First, convert 3 kg 600 g to kilograms: 3 kg 600 g = 3 kg + (600 g / 1000) kg = 3.6 kg Now, perform the subtraction: 5 kg - 3.6 kg = 1.4 kg

3. 3 kg 800 g + 4 kg 300 g: Convert 3 kg 800 g and 4 kg 300 g to kilograms: 3 kg 800 g = 3 kg + (800 g / 1000) kg = 3.8 kg 4 kg 300 g = 4 kg + (300 g / 1000) kg = 4.3 kg Perform the addition: 3.8 kg + 4.3 kg = 8.1 kg

4. 8 kg 800 g - 5 kg 600 g: Convert 8 kg 800 g and 5 kg 600 g to kilograms: 8 kg 800 g = 8 kg + (800 g / 1000) kg = 8.8 kg 5 kg 600 g = 5 kg + (600 g / 1000) kg = 5.6 kg Perform the subtraction: 8.8 kg - 5.6 kg = 3.2 kg

So, the results are:

1. 3 kg + 2 kg 400 g = 5.4 kg
2. 5 kg - 3 kg 600 g = 1.4 kg
3. 3 kg 800 g + 4 kg 300 g = 8.1 kg
4. 8 kg 800 g - 5 kg 600 g = 3.2 kg
