Answer 1

1. 396 см = 39 дм 6 см
2. 229см<2 м3дм9см
3. 586см>4м8дм6см
4. 2м5щм7см>25дм6см

Answer 2

To simplify and convert all the measurements to a single unit (centimeters), we need to add up the values in each unit:

1. 396 cm
2. 39 dm 6 cm (1 dm = 10 cm)
3. 229 cm
4. 2 m 3 dm 9 cm (1 m = 100 cm, 1 dm = 10 cm)
5. 586 cm
6. 4 m 8 dm 6 cm (1 m = 100 cm, 1 dm = 10 cm)
7. 2 m 5 dm 7 cm (1 m = 100 cm, 1 dm = 10 cm)
8. 25 dm 6 cm (1 dm = 10 cm)

Let's convert them all to centimeters:

1. 396 cm
2. 39 dm * 10 cm/dm + 6 cm = 390 cm + 6 cm = 396 cm
3. 229 cm
4. 2 m * 100 cm/m + 3 dm * 10 cm/dm + 9 cm = 200 cm + 30 cm + 9 cm = 239 cm
5. 586 cm
6. 4 m * 100 cm/m + 8 dm * 10 cm/dm + 6 cm = 400 cm + 80 cm + 6 cm = 486 cm
7. 2 m * 100 cm/m + 5 dm * 10 cm/dm + 7 cm = 200 cm + 50 cm + 7 cm = 257 cm
8. 25 dm * 10 cm/dm + 6 cm = 250 cm + 6 cm = 256 cm

Now, let's add all the converted values together:

396 cm + 396 cm + 229 cm + 239 cm + 586 cm + 486 cm + 257 cm + 256 cm = 3045 cm

So, the total length is 3045 centimeters.
