Question

4м-6дм= 1кг-580г= 3год-8хв= 2м:5=

Answer 1

1)

1см = 1см

1дм = 10см

1м = 100см

4м - 6дм = 400см - 60см = 340см = 34дм = 3.4м.

2)

1г = 1000мг

1кг = 1000г

1т = 1000кг

1кг - 580г = 1000г - 580г = 420,000мг = 420г = 0.42кг.

3)

1сек = 100мсек

1хв = 60сек

1год = 60хв

3год - 8хв = 180хв - 8хв = 103,200мсек = 1032сек = 172хв = 2год 52хв.

4)

1см = 1см

1дм = 10см

1м = 100см

2м : 5 = 200см : 5 = 40см = 4дм = 0.4м.

Answer 2

To solve these equations, let's break them down one by one:

1. 4м - 6дм: We need to subtract 6 decimeters (дм) from 4 meters (м). Since 1 meter is equal to 10 decimeters, we can convert 4 meters to decimeters by multiplying it by 10: 4 м = 4 * 10 дм = 40 дм Now we can perform the subtraction: 40 дм - 6 дм = 34 дм

   Therefore, 4м - 6дм is equal to 34 дм.

2. 1кг - 580г: We need to subtract 580 grams (г) from 1 kilogram (кг). Since 1 kilogram is equal to 1000 grams, we can perform the subtraction directly: 1 кг - 580 г = 1000 г - 580 г = 420 г

   Therefore, 1кг - 580г is equal to 420 г.

3. 3год - 8хв: We need to subtract 8 hours (хв) from 3 years (год). Since 1 year has 365 days and 1 day has 24 hours, we can convert the years to hours: 3 год = 3 * 365 дней * 24 часа = 26,280 часов Now we can perform the subtraction: 26,280 часов - 8 часов = 26,272 часов

   Therefore, 3год - 8хв is equal to 26,272 часов.

4. 2м:5: We need to divide 2 meters (м) by 5. Since there are no other units involved, we can directly perform the division: 2 м / 5 = 0.4 м

   Therefore, 2м:5 is equal to 0.4 м.
