Question

4дм= см ; 300см= дм ;250 см =дм см ; 2дм 6см =см ​

Answer 1

4дм = 40см

300см = 30дм

250см = 25дм

2дм 6см = 26см

Answer 2

1)40см 2)30дм 3)25дм 4)26см

Answer 3

To convert between different units of length, you can use the following conversion factors:

1 decimeter (dm) = 10 centimeters (cm) 1 centimeter (cm) = 0.1 decimeter (dm)

Let's use these conversion factors to convert the given measurements:

1. 4 dm = ? cm To convert decimeters to centimeters, multiply by 10: 4 dm = 4 * 10 cm = 40 cm

2. 300 cm = ? dm To convert centimeters to decimeters, divide by 10: 300 cm = 300 / 10 dm = 30 dm

3. 250 cm = ? dm cm We are not given any specific conversion to use here, but let's assume it means we need to express 250 cm in decimeters and centimeters. We can do this step by step: 250 cm = 250 / 10 dm = 25 dm Remaining centimeters: 250 cm - (25 dm * 10 cm/dm) = 0 cm

So, 250 cm is equal to 25 decimeters (dm) and 0 centimeters (cm).

4. 2 dm 6 cm = ? cm First, convert 2 dm to centimeters: 2 dm = 2 * 10 cm = 20 cm

Now add the 6 centimeters: 2 dm 6 cm = 20 cm + 6 cm = 26 cm

Therefore:

• 4 dm = 40 cm
• 300 cm = 30 dm
• 250 cm = 25 dm 0 cm
• 2 dm 6 cm = 26 cm
