Question

8км250м+3км139м= 25м39см-4м26см= 6кг150г+2кг375г= 15кг750г-7кг275г=

Answer 1

8 км 250 м + 3 км 139м=11км389м
25 м 39 см - 4 м 26см=24м613см
6 кг 150 г + 2 кг 375г=8кг525г
15 кг 750 г - 7кг 275г=8кг475г

Answer 2

Let's calculate each expression step by step:

1. 8 km 250 m + 3 km 139 m:

To add the distances, we start by adding the kilometers and then the meters separately:

8 km + 3 km = 11 km 250 m + 139 m = 389 m

Therefore, 8 km 250 m + 3 km 139 m equals 11 km 389 m.

2. 25 m 39 cm - 4 m 26 cm:

To subtract the distances, we start by subtracting the meters and then the centimeters separately:

25 m - 4 m = 21 m 39 cm - 26 cm = 13 cm

Therefore, 25 m 39 cm - 4 m 26 cm equals 21 m 13 cm.

3. 6 kg 150 g + 2 kg 375 g:

To add the weights, we start by adding the kilograms and then the grams separately:

6 kg + 2 kg = 8 kg 150 g + 375 g = 525 g

Therefore, 6 kg 150 g + 2 kg 375 g equals 8 kg 525 g.

4. 15 kg 750 g - 7 kg 275 g:

To subtract the weights, we start by subtracting the kilograms and then the grams separately:

15 kg - 7 kg = 8 kg 750 g - 275 g = 475 g

Therefore, 15 kg 750 g - 7 kg 275 g equals 8 kg 475 g.

So the results are:

8 km 250 m + 3 km 139 m = 11 km 389 m 25 m 39 cm - 4 m 26 cm = 21 m 13 cm 6 kg 150 g + 2 kg 375 g = 8 kg 525 g 15 kg 750 g - 7 kg 275 g = 8 kg 475 g
