Answer 1

64 мм < 7 см 
4 см 3 мм < 45 мм
25 см = 2 дм 5 см
25 м= 250 дм 

3 м 4 см 2 мм < 3 м 5 см
948 мм < 94 дм 8 мм
75 см 7 мм > 7 Дм
6 дм 8 см > 60 см 8 мм 
5 м 4 см  < 50 дм 4 см 
(Пожалуйста :D)

Answer 2

Calculation of Lengths

To solve the given equations, let's convert all the measurements to a common unit, such as millimeters (mm). Then we can compare the lengths.

1. 64 mm + 7 cm: - 7 cm = 70 mm (1 cm = 10 mm) - 64 mm + 70 mm = 134 mm.

2. 4 cm + 3 mm: - 4 cm = 40 mm (1 cm = 10 mm) - 40 mm + 3 mm = 43 mm.

3. 45 mm = 25 cm: - 25 cm = 250 mm (1 cm = 10 mm) - 45 mm = 250 mm.

4. 2 dm + 5 cm: - 2 dm = 200 mm (1 dm = 100 mm) - 5 cm = 50 mm (1 cm = 10 mm) - 200 mm + 50 mm = 250 mm.

5. 25 m = 2500 dm: - 2500 dm = 25000 cm = 250000 mm (1 m = 10 dm, 1 dm = 10 cm, 1 cm = 10 mm) - 25 m = 250000 mm.

6. 3 m + 4 cm + 2 mm: - 3 m = 3000 mm (1 m = 1000 mm) - 4 cm = 40 mm (1 cm = 10 mm) - 3000 mm + 40 mm + 2 mm = 3042 mm.

7. 3 m + 5 cm: - 3 m = 3000 mm (1 m = 1000 mm) - 5 cm = 50 mm (1 cm = 10 mm) - 3000 mm + 50 mm = 3050 mm.

8. 948 mm = 94 dm + 8 mm: - 94 dm = 9400 mm (1 dm = 100 mm) - 9400 mm + 8 mm = 9408 mm.

9. 75 cm + 7 mm: - 75 cm = 750 mm (1 cm = 10 mm) - 750 mm + 7 mm = 757 mm.

10. 7 dm = 6 dm + 8 cm: - 6 dm = 600 mm (1 dm = 100 mm) - 8 cm = 80 mm (1 cm = 10 mm) - 600 mm + 80 mm = 680 mm.

11. 60 cm + 8 mm = 5 m + 4 cm: - 60 cm = 600 mm (1 cm = 10 mm) - 8 mm = 8 mm - 5 m = 5000 mm (1 m = 1000 mm) - 4 cm = 40 mm (1 cm = 10 mm) - 600 mm + 8 mm = 5000 mm + 40 mm = 5048 mm.

12. 50 dm + 4 cm: - 50 dm = 5000 mm (1 dm = 100 mm) - 4 cm = 40 mm (1 cm = 10 mm) - 5000 mm + 40 mm = 5040 mm.

Therefore, the results are as follows:

1. 64 mm + 7 cm = 134 mm. 2. 4 cm + 3 mm = 43 mm. 3. 45 mm = 25 cm. 4. 2 dm + 5 cm = 250 mm. 5. 25 m = 250000 mm. 6. 3 m + 4 cm + 2 mm = 3042 mm. 7. 3 m + 5 cm = 3050 mm. 8. 948 mm = 9408 mm. 9. 75 cm + 7 mm = 757 mm. 10. 7 dm = 6 dm + 8 cm = 680 mm. 11. 60 cm + 8 mm = 5 m + 4 cm = 5048 mm. 12. 50 dm + 4 cm = 5040 mm.

I hope this helps! Let me know if you have any further questions.
