Answer 1

1. 234+511=745 см
2. 234+144=378 см
3. 450+303=753 см
4.359-144=215 см
5. 675-302=373 см
6. 697-245=452 см
Перепроверь на калькуляторе, может где-то ошиблась

Answer 2

Let's perform the calculations step by step:

1. 2м34см + 5м11см: 2 meters + 5 meters = 7 meters 34 centimeters + 11 centimeters = 45 centimeters

The result is 7 meters and 45 centimeters.

2. 2м3дм4см + 1м4дм4см: 2 meters + 1 meter = 3 meters 3 decimeters + 4 decimeters = 7 decimeters 4 centimeters + 4 centimeters = 8 centimeters

The result is 3 meters, 7 decimeters, and 8 centimeters.

3. 45дм + 3м3см: 45 decimeters = 4 meters and 5 decimeters (since 10 decimeters = 1 meter) 3 centimeters = 0 meters and 3 centimeters

Adding them up: 4 meters + 0 meters = 4 meters 5 decimeters + 0 meters = 5 decimeters 0 centimeters + 3 centimeters = 3 centimeters

The result is 4 meters, 5 decimeters, and 3 centimeters.

4. 3м5дм9см - 1м4дм4см: 3 meters - 1 meter = 2 meters 5 decimeters - 4 decimeters = 1 decimeter 9 centimeters - 4 centimeters = 5 centimeters

The result is 2 meters, 1 decimeter, and 5 centimeters.

5. 67дм5см - 3м2см: 67 decimeters = 6 meters and 7 decimeters 5 centimeters - 2 centimeters = 3 centimeters

The result is 6 meters, 7 decimeters, and 3 centimeters.

6. 6м9дм7см - 2м45см: 6 meters - 2 meters = 4 meters 9 decimeters - 4 decimeters = 5 decimeters 7 centimeters - 45 centimeters (borrowing 1 meter) = 62 centimeters (62 centimeters = 6 decimeters and 2 centimeters)

The result is 4 meters, 5 decimeters, and 6 centimeters.

So, the final results are:

1. 7 meters and 45 centimeters
2. 3 meters, 7 decimeters, and 8 centimeters
3. 4 meters, 5 decimeters, and 3 centimeters
4. 2 meters, 1 decimeter, and 5 centimeters
5. 6 meters, 7 decimeters, and 3 centimeters
6. 4 meters, 5 decimeters, and 6 centimeters
