Question

6м2* 60дм2 4дм2* 900см2 800см2* 8дм2

Answer 1

600дм²>60дм²
400см²<900см²
8дм²=8дм²

Answer 2

To simplify the given expressions, let's convert all the measurements to a consistent unit (let's choose square centimeters), perform the calculations, and then convert back to the desired units.

1. 6м2 (square meters) to square centimeters: 1 square meter = 10000 square centimeters 6 square meters = 6 * 10000 = 60000 square centimeters

2. 60дм2 (square decimeters) to square centimeters: 1 square decimeter = 100 square centimeters 60 square decimeters = 60 * 100 = 6000 square centimeters

3. 4дм2 (square decimeters) to square centimeters: 4 square decimeters = 4 * 100 = 400 square centimeters

4. 900см2 (square centimeters) - this one is already in square centimeters.

5. 800см2 (square centimeters) to square decimeters: 1 square decimeter = 100 square centimeters 800 square centimeters = 800 / 100 = 8 square decimeters

6. 8дм2 (square decimeters) to square centimeters: 8 square decimeters = 8 * 100 = 800 square centimeters

Now let's perform the calculations:

60000 + 6000 + 400 + 900 - 800 + 800 = 62300 square centimeters

Finally, if you want the result in different units:

62300 square centimeters = 6.23м2 (square meters)
