Answer 2

Пошаговое объяснение:

76дм=7м6дм

23см= 2дм 3 см

34см= 3дм 4см

57дм=5м7дм

70см-3дм(30см)=40см

65м(650дм)+40дм=690дм

4дм(40см)+40см=80см

40см+20см=60см

1м(100см)-78см=22см

90дм-70дм=20дм

Answer 3

To convert the given measurements, let's use the following conversion factors:

1 meter (м) = 10 decimeters (дм) 1 decimeter (дм) = 10 centimeters (см)

Now, let's perform the conversions step by step:

1. 76 дм = ? м_дм

Since 1 meter is equal to 10 decimeters, we can divide 76 by 10 to convert it to meters: 76 дм = 7 м + 6 дм

Therefore, 76 дм is equal to 7 м 6 дм.

2. 23 см = ? дм_см

We need to convert centimeters to decimeters. Since 1 decimeter is equal to 10 centimeters, we can divide 23 by 10: 23 см = 2 дм + 3 см

Therefore, 23 см is equal to 2 дм 3 см.

3. 34 см = ? дм_см

Using the same conversion factor, we divide 34 by 10 to convert it to decimeters: 34 см = 3 дм + 4 см

Therefore, 34 см is equal to 3 дм 4 см.

4. 57 дм = ? м_дм

Since 1 meter is equal to 10 decimeters, we can divide 57 by 10 to convert it to meters: 57 дм = 5 м + 7 дм

Therefore, 57 дм is equal to 5 м 7 дм.

5. 70 см - 3 дм = ?

To subtract, we need to ensure that the units are the same. Let's convert 70 см to decimeters first: 70 см = 7 дм + 0 см

Now we can subtract 3 дм from 7 дм: 7 дм - 3 дм = 4 дм

Therefore, 70 см - 3 дм is equal to 4 дм.

6. 65 м + 40 дм = ?

Since 1 meter is equal to 10 decimeters, we can add 40 дм directly to the meters: 65 м + 40 дм = 65 м + 4 дм

Therefore, 65 м + 40 дм is equal to 65 м 4 дм.

7. 4 дм + 40 см = ?

We need to convert centimeters to decimeters before adding them: 40 см = 4 дм + 0 см

Now we can add 4 дм to 4 дм: 4 дм + 4 дм = 8 дм

Therefore, 4 дм + 40 см is equal to 8 дм.

8. 40 см + 20 см = ?

We can simply add the centimeters together: 40 см + 20 см = 60 см

Therefore, 40 см + 20 см is equal to 60 см.

9. 1 м - 78 см = ?

We need to convert centimeters to meters before subtracting them: 78 см = 7 дм + 8 см

Now we can subtract 7 дм from 1 м: 1 м - 7 дм = 0 м + 3 дм

Therefore, 1 м - 78 см is equal to 0 м 3 дм.

10. 90 д - 70 дм = ?

We need to convert decimeters to decameters before subtracting them: 70 дм = 7 д

Now we can subtract 7 д from 90 д: 90 д - 7 д = 83 д

Therefore, 90 д - 70 дм is equal to 83 д.
