Answer 1

1) 2 м и 3 дм - 23 дм, 230 см, 2300 мм
2 м - 20 дм, 200 см, 2000 мм
3 дм - 30 см, 300 мм
2) 900 кв.см > 100 кв.см
3) да
4) 45 мин., да

Answer 2

Answer:

To answer your questions:

1. 2 m and 3 dm is equal to 230 cm. To convert meters to centimeters, we multiply by 100, and to convert decimeters to centimeters, we multiply by 10. Therefore, 2 m is equal to 200 cm, and 3 dm is equal to 30 cm. Adding these together, we get 200 cm + 30 cm = 230 cm.

2. 900 square centimeters is indeed greater than 10 square decimeters. To compare the two, we need to convert square decimeters to square centimeters. Since 1 square decimeter is equal to 100 square centimeters, 10 square decimeters is equal to 10 * 100 = 1000 square centimeters. Therefore, 900 square centimeters is less than 1000 square centimeters.

3. Yes, a tonne is 10 times greater than a centner. A tonne is equal to 1000 kilograms, while a centner is equal to 100 kilograms. Therefore, a tonne is 10 times greater than a centner.

4. From 11:35 AM to 12:20 PM, there is a time span of 45 minutes, which is indeed greater than 40 minutes. To calculate the time difference, we subtract the starting time from the ending time: 12:20 PM - 11:35 AM = 45 minutes.
