Answer 1

1. 529мм.
2. 300 см.
3. 1350см.
4. 124022см.
5.10015м.
6. 21920дм.

Answer 2

1.5 дм 2см 9 мм=529 мм

2.3м=300см

3.13 м 5 дм=135 см

4.124м 22см=12422см

5.10км 15м=10015м

6. 2 км 192м=21920дм

Answer 3

To perform the conversions, we need to know the relationships between different units of length:

1 decimeter (dm) = 10 centimeters (cm) 1 meter (m) = 10 decimeters (dm) = 100 centimeters (cm) 1 kilometer (km) = 1000 meters (m)

Let's start with the conversions:

1. 5 dm 2 cm 9 mm = ? mm To convert to millimeters, we need to add up all the lengths: 5 dm = 50 cm 2 cm = 2 cm 9 mm = 9 mm

Total length = 50 cm + 2 cm + 9 mm = 50 cm + 2 cm + 0.9 cm = 52 cm + 0.9 cm = 52.9 cm

Therefore, 5 dm 2 cm 9 mm is equal to 52.9 mm.

2. 3 m = ? cm To convert meters to centimeters, we need to multiply by 100: 3 m = 3 * 100 cm = 300 cm

Therefore, 3 meters is equal to 300 centimeters.

3. 13 m 5 dm = ? cm To convert to centimeters, we need to add up all the lengths: 13 m = 13 * 100 cm = 1300 cm 5 dm = 5 * 10 cm = 50 cm

Total length = 1300 cm + 50 cm = 1350 cm

Therefore, 13 m 5 dm is equal to 1350 centimeters.

4. 124 m 22 cm = ? cm To convert to centimeters, we need to add up all the lengths: 124 m = 124 * 100 cm = 12400 cm 22 cm = 22 cm

Total length = 12400 cm + 22 cm = 12422 cm

Therefore, 124 meters 22 centimeters is equal to 12422 centimeters.

5. 10 km 15 m = ? m To convert kilometers to meters, we need to multiply by 1000: 10 km = 10 * 1000 m = 10000 m 15 m = 15 m

Total length = 10000 m + 15 m = 10015 m

Therefore, 10 kilometers 15 meters is equal to 10015 meters.

6. 2 km 192 m = ? dm To convert to decimeters, we first need to convert everything to meters and then to decimeters: 2 km = 2 * 1000 m = 2000 m 192 m = 192 m

Total length = 2000 m + 192 m = 2192 m 1 m = 10 dm 2192 m = 2192 * 10 dm = 21920 dm

Therefore, 2 kilometers 192 meters is equal to 21920 decimeters.
