Question

32дм+15см=? 27см+3дм=. 23см+15мм=. 23мм+62мм= 3м+14дм= 15мм+3см=

Answer 1

Нужно все перевести в одинаковые величины
32дм= 320см        320+15=335см=33дм и 5см
27см+30см=57см
15мм+230мм=235мм
30дм+14дм=44дм
15мм+30мм=45мм

Answer 2

32дм+15см=335см
27см+3дм=57см
23см+15мм=245мм
23мм+62мм=85мм
3м+14дм=44дм
15мм+3см=45мм

Answer 3

To perform the calculations, let's convert all the measurements to the same unit before adding them.

1. 32 dm + 15 cm: To convert cm to dm, we divide by 10. 15 cm = 15/10 dm = 1.5 dm Now we can add: 32 dm + 1.5 dm = 33.5 dm

2. 27 cm + 3 dm: To convert dm to cm, we multiply by 10. 3 dm = 3 * 10 cm = 30 cm Now we can add: 27 cm + 30 cm = 57 cm

3. 23 cm + 15 mm: To convert mm to cm, we divide by 10. 15 mm = 15/10 cm = 1.5 cm Now we can add: 23 cm + 1.5 cm = 24.5 cm

4. 23 mm + 62 mm: We can directly add these measurements in millimeters: 23 mm + 62 mm = 85 mm

5. 3 m + 14 dm: To convert meters to decimeters, we multiply by 10. 3 m = 3 * 10 dm = 30 dm Now we can add: 30 dm + 14 dm = 44 dm

6. 15 mm + 3 cm: To convert cm to mm, we multiply by 10. 3 cm = 3 * 10 mm = 30 mm Now we can add: 15 mm + 30 mm = 45 mm

Here are the results of the calculations:

1. 32 dm + 15 cm = 33.5 dm
2. 27 cm + 3 dm = 57 cm
3. 23 cm + 15 mm = 24.5 cm
4. 23 mm + 62 mm = 85 mm
5. 3 m + 14 dm = 44 dm
6. 15 mm + 3 cm = 45 mm
