Question

3м6дм+4м2дм 8м9дм-3м5дм 5м6дм+2м4дм 7м-3м8дм

Answer 1

1)3м6дм=360см
4м2дм=420см
360+420=780см=7м8дм

8м9дм=890см
3м5дм=350см
890-350=540см=5м4дм

5м6дм=560см
2м4дм=240см
560+240=800см=8м

7м=700см
3м8дм=380см
700-380=320см=3м2дм

Answer 2

3м6дм+4м2дм = 1м5см
8м9дм-3м5дм= 9м
5м6дм +2м4дм=1м7дм
7м--3м8дм = 4м8дм

Answer 3

To add or subtract measurements, we need to ensure that the units are consistent. In this case, we are dealing with meters (м) and decimeters (дм), so we need to convert everything to the same unit before performing the operations.

1 meter (м) = 10 decimeters (дм)

Let's perform the given operations step by step:

Addition:

1. 3м6дм + 4м2дм 3 meters + 4 meters = 7 meters 6 decimeters + 2 decimeters = 8 decimeters Therefore, 3м6дм + 4м2дм = 7 meters 8 decimeters (7м8дм)

2. 8м9дм - 3м5дм 8 meters - 3 meters = 5 meters 9 decimeters - 5 decimeters = 4 decimeters Therefore, 8м9дм - 3м5дм = 5 meters 4 decimeters (5м4дм)

3. 5м6дм + 2м4дм 5 meters + 2 meters = 7 meters 6 decimeters + 4 decimeters = 10 decimeters (which can be converted to 1 meter since 1 meter = 10 decimeters) Therefore, 5м6дм + 2м4дм = 8 meters (7м1дм)

4. 7м - 3м8дм 7 meters - 3 meters = 4 meters 8 decimeters can be converted to 0 meters and 8 decimeters (0м8дм) Therefore, 7м - 3м8дм = 4 meters 8 decimeters (4м8дм)

Subtraction:

1. 3м6дм + 4м2дм 3 meters + 4 meters = 7 meters 6 decimeters + 2 decimeters = 8 decimeters Therefore, 3м6дм + 4м2дм = 7 meters 8 decimeters (7м8дм)

2. 8м9дм - 3м5дм 8 meters - 3 meters = 5 meters 9 decimeters - 5 decimeters = 4 decimeters Therefore, 8м9дм - 3м5дм = 5 meters 4 decimeters (5м4дм)

3. 5м6дм + 2м4дм 5 meters + 2 meters = 7 meters 6 decimeters + 4 decimeters = 10 decimeters (which can be converted to 1 meter since 1 meter = 10 decimeters) Therefore, 5м6дм + 2м4дм = 8 meters (7м1дм)

4. 7м - 3м8дм 7 meters - 3 meters = 4 meters 8 decimeters can be converted to 0 meters and 8 decimeters (0м8дм) Therefore, 7м - 3м8дм = 4 meters 8 decimeters (4м8дм)

The final results after addition and subtraction are as follows:

• 3м6дм + 4м2дм = 7 meters 8 decimeters (7м8дм)
• 8м9дм - 3м5дм = 5 meters 4 decimeters (5м4дм)
• 5м6дм + 2м4дм = 8 meters (7м1дм)
• 7м - 3м8дм = 4 meters 8 decimeters (4м8дм)
