Conversion Questions:

1. 890 коп = руб коп To convert 890 коп to руб коп, we need to divide 890 by 100 to get the number of rubles and take the remainder as the number of kopeks. Therefore, 890 коп is equal to 8 руб 90 коп.

2. 3 мин 40 сек = с 12ч = мин To convert 3 minutes 40 seconds to seconds, we multiply 3 by 60 (to convert minutes to seconds) and add 40. Therefore, 3 minutes 40 seconds is equal to 220 seconds.

To convert 220 seconds to minutes, we divide 220 by 60. Therefore, 220 seconds is equal to 3 minutes and 40 seconds.

To convert 12 hours to minutes, we multiply 12 by 60. Therefore, 12 hours is equal to 720 minutes.

Adding the two values together, 220 seconds + 720 minutes = 940 minutes.

3. 8м 42дм = см To convert 8 meters to centimeters, we multiply 8 by 100. Therefore, 8 meters is equal to 800 centimeters.

To convert 42 decimeters to centimeters, we multiply 42 by 10. Therefore, 42 decimeters is equal to 420 centimeters.

Adding the two values together, 800 centimeters + 420 centimeters = 1220 centimeters.

4. 2 руб = коп To convert 2 rubles to kopeks, we multiply 2 by 100. Therefore, 2 rubles is equal to 200 kopeks.

5. 42,000 дм = М To convert 42,000 decimeters to meters, we divide 42,000 by 1,000. Therefore, 42,000 decimeters is equal to 42 meters.

6. 3 см в квадрате = мм To convert 3 square centimeters to square millimeters, we multiply 3 by 100. Therefore, 3 square centimeters is equal to 300 square millimeters.

7. 360 сек = мин To convert 360 seconds to minutes, we divide 360 by 60. Therefore, 360 seconds is equal to 6 minutes.

8. 3 кг = г To convert 3 kilograms to grams, we multiply 3 by 1,000. Therefore, 3 kilograms is equal to 3,000 grams.
