Сравни 1дм *10см 8см*10 см 9см*1дм 8см+2см*1 дм 9см-8см*1 см 5см+5см*1 см 1 дм*1см+9см 1см*1см+1см 1 дм*10см- 1см помогите пожалуйста

Answer 1

1 дм = 10 см
8 см ≤ 10  см
9 см ≤ 1 дм
8+2 см = 1 дм
9-8 см = 1 см
5+5 см ≥ 1 см
1 дм = 1+ 9 см
1 см ≤  1+1 см
1 дм ≥ 10-1 см

Comparison of Measurements

To compare the given measurements, let's convert them into a consistent unit. Since all the measurements are in different units (decimeters, centimeters, and millimeters), we need to convert them to a common unit before comparing.

Here are the given measurements: - 1 dm * 10 cm - 8 cm * 10 cm - 9 cm * 1 dm - 8 cm + 2 cm * 1 dm - 9 cm - 8 cm * 1 cm - 5 cm + 5 cm * 1 cm - 1 dm * 1 cm + 9 cm - 1 cm * 1 cm + 1 cm - 1 dm * 10 cm - 1 cm

Let's convert these measurements to a common unit, such as centimeters, for easier comparison.

1. 1 dm * 10 cm = 10 cm * 10 cm = 100 cm^2 2. 8 cm * 10 cm = 80 cm^2 3. 9 cm * 1 dm = 9 cm * 10 cm = 90 cm^2 4. 8 cm + 2 cm * 1 dm = 8 cm + 2 cm * 10 cm = 8 cm + 20 cm = 28 cm 5. 9 cm - 8 cm * 1 cm = 9 cm - 8 cm = 1 cm 6. 5 cm + 5 cm * 1 cm = 5 cm + 5 cm = 10 cm 7. 1 dm * 1 cm + 9 cm = 10 cm * 1 cm + 9 cm = 10 cm + 9 cm = 19 cm 8. 1 cm * 1 cm + 1 cm = 1 cm^2 + 1 cm = 2 cm 9. 1 dm * 10 cm - 1 cm = 10 cm * 10 cm - 1 cm = 100 cm^2 - 1 cm = 99 cm^2

Now, let's compare the measurements:

- 100 cm^2 > 80 cm^2 - 100 cm^2 > 90 cm^2 - 100 cm^2 > 28 cm - 1 cm < 100 cm^2 - 10 cm > 1 cm - 19 cm > 2 cm - 99 cm^2 > 1 cm

Based on the comparison, we can conclude that the measurements in order from smallest to largest are: 1. 1 cm 2. 2 cm 3. 28 cm 4. 80 cm^2 5. 90 cm^2 6. 99 cm^2 7. 100 cm^2 8. 10 cm 9. 19 cm

Please note that the comparison is based on the converted measurements in centimeters.
