Answer 2

To convert the given measurements, we can use the following conversion factors:

1 decimeter (dm) = 10 centimeters (cm) 1 meter (m) = 100 centimeters (cm) 1 meter (m) = 10 decimeters (dm) 1 minute (min) = 60 seconds (s) 1 hour (h) = 60 minutes (min)

Let's calculate the conversions:

1. 6 dm = ? mm Since 1 dm = 10 cm and 1 cm = 10 mm, we can multiply: 6 dm = 6 * 10 cm = 60 cm = 60 * 10 mm = 600 mm Therefore, 6 dm is equal to 600 mm.

2. 52 dm = ? m^2 cm Since 1 dm = 0.1 m, we can convert dm to m: 52 dm = 52 * 0.1 m = 5.2 m To convert m^2 to cm^2, we multiply by 10000: 5.2 m^2 = 5.2 * 10000 cm^2 = 52000 cm^2 Therefore, 52 dm is equal to 52000 cm^2.

3. 472 cm = ? dm^2 cm Since 1 dm = 10 cm, we can convert cm to dm: 472 cm = 472 / 10 dm = 47.2 dm To represent dm^2 and cm together, we can write it as 47 dm 2 cm. Therefore, 472 cm is equal to 47 dm^2 cm.

4. 8 m 5 cm = ? m^2 dm Since 1 m = 10 dm and 1 cm = 0.01 m, we can convert cm to dm: 8 m 5 cm = 8 m + (5 cm * 0.01 m/cm) = 8 m + 0.05 m = 8.05 m To represent m^2 and dm together, we can write it as 8 m 5 dm. Therefore, 8 m 5 cm is equal to 8 m 5 dm.

5. 305 s = ? min s Since 1 min = 60 s, we can divide: 305 s = 305 / 60 min = 5 min + 5 s Therefore, 305 s is equal to 5 min 5 s.

6. 148 min = ? h min Since 1 h = 60 min, we can divide: 148 min = 148 / 60 h = 2 h + 28 min Therefore, 148 min is equal to 2 h 28 min.

In summary:

1. 6 dm = 600 mm
2. 52 dm = 52000 cm^2
3. 472 cm = 47 dm^2 cm
4. 8 m 5 cm = 8 m 5 dm
5. 305 s = 5 min 5 s
6. 148 min = 2 h 28 min
