Question

Дециметрмен: 7 м 6 дм; 5 м 9 дм, 2 м 4 дм, 1 км 5 дм, 7 км 29 м, 6 км 4 дм, 8 км 2 дм, 5 км 3 м, 3 км 4 м 5 дм, 7 км 7 м 7дм.

Answer 1

7 м 6 дм= 7000см+60см=7060см=706 дм;

5 м 9 дм=509дм

2 м 4 дм=204дм,

1 км 5 дм=1 0006дм,

7 км 29 м=7029м

6 км 4 дм=60004,

8 км 2 дм=80002,

5 км 3 м=5003,

3 км 4 м 5 дм=3054,

7 км 7 м 7дм=7000+70+7=7077

Answer 2

It looks like you've provided a list of distances in various units. Let's convert all of them to decimeters for consistency:

1 meter (m) = 10 decimeters (dm) 1 kilometer (km) = 1000 meters = 10000 decimeters

Let's convert each distance to decimeters:

1. 7 m 6 dm = (7 * 10) + 6 = 70 + 6 = 76 dm
2. 5 m 9 dm = (5 * 10) + 9 = 50 + 9 = 59 dm
3. 2 m 4 dm = (2 * 10) + 4 = 20 + 4 = 24 dm
4. 1 km 5 dm = (1 * 10000) + (5 * 10) = 10000 + 50 = 10050 dm
5. 7 km 29 m = (7 * 10000) + (29 * 10) = 70000 + 290 = 70290 dm
6. 6 km 4 dm = (6 * 10000) + (4 * 10) = 60000 + 40 = 60040 dm
7. 8 km 2 dm = (8 * 10000) + (2 * 10) = 80000 + 20 = 80020 dm
8. 5 km 3 m = (5 * 10000) + (3 * 10) = 50000 + 30 = 50030 dm
9. 3 km 4 m 5 dm = (3 * 10000) + (4 * 10) + 5 = 30000 + 40 + 5 = 30045 dm
10. 7 km 7 m 7 dm = (7 * 10000) + (7 * 10) + 7 = 70000 + 70 + 7 = 70077 dm

So the distances in decimeters are:

1. 76 dm
2. 59 dm
3. 24 dm
4. 10050 dm
5. 70290 dm
6. 60040 dm
7. 80020 dm
8. 50030 dm
9. 30045 dm
10. 70077 dm
