Question

1дм*100см, 3дм*50см, 1м*90см, 40см*3дм, 6ди*70см, 10дм*100см знаки <>=

Answer 1

1 дм < 100 см
3 дм < 50 см
1 м > 90 см
40 см > 3 дм
6 дм < 70 см
10 дм = 100 см

Answer 2

1дм{100см
10см{100см

3дм{50см
30см{50см

1м}90см
100м}90см


40см}3дм
40см}30см

60дм}70см
600см}70см

10дм=100см
100см=100см

Answer 3

To compare the given measurements using the symbols "<", ">", or "=", we need to convert all of them to the same unit. Let's choose centimeters (cm) as the common unit of measurement.

Given measurements: 1 дм * 100 см = 100 cm * 100 cm = 10000 square cm 3 дм * 50 см = 30 cm * 50 cm = 1500 square cm 1 м * 90 см = 100 cm * 90 cm = 9000 square cm 40 см * 3 дм = 40 cm * 30 cm = 1200 square cm 6 дм * 70 см = 60 cm * 70 cm = 4200 square cm 10 дм * 100 см = 100 cm * 100 cm = 10000 square cm

Now, let's compare the areas:

10000 square cm > 10000 square cm (equal) 10000 square cm > 9000 square cm 10000 square cm > 4200 square cm 9000 square cm > 1500 square cm 1500 square cm > 1200 square cm

Final comparisons: 1 дм * 100 см = 10,000 square cm 3 дм * 50 см = 1,500 square cm 1 м * 90 см = 9,000 square cm 40 см * 3 дм = 1,200 square cm 6 дм * 70 см = 4,200 square cm 10 дм * 100 см = 10,000 square cm

The sorted measurements from largest to smallest area are:

1. 1 дм * 100 см (10,000 square cm)
2. 10 дм * 100 см (10,000 square cm)
3. 1 м * 90 см (9,000 square cm)
4. 6 дм * 70 см (4,200 square cm)
5. 3 дм * 50 см (1,500 square cm)
6. 40 см * 3 дм (1,200 square cm)
