Question

Выполни действия: 1 кг 300 г - 890 г = ? 63 м (в кубе) 89 дм (в кубе) * 147 = ? 17 ч 48 мин + 12 ч 36 мин = ? 8 лет 5 мес. + 12 лет 9 мес. = ?

Answer 1

1 куб метр=1 000 куб дм 
(63000куб дм+89 куб.дм)*147=63089*147=9274083 куб дм=9274 ку.м83 куб.дм
17 ч 48 мин + 12 ч 36 мин=29ч84ми=1 день6часов24 мин
8 лет 5 мес + 12 лет 9 мес=20 лет 14 месяцев=21 год 2 месяца

Answer 2

1 кг 300 г - 890 г = ? To solve this, we need to subtract 890 grams from 1 kilogram and 300 grams.

1 kilogram is equal to 1000 grams. So, 1 kilogram and 300 grams is equal to 1300 grams.

Subtracting 890 grams from 1300 grams gives us 410 grams.

Therefore, 1 kg 300 g - 890 g = 410 g.

63 м (в кубе) 89 дм (в кубе) * 147 = ? To solve this, we need to multiply 63 meters cubed by 89 decimeters cubed, and then multiply the result by 147.

1 meter cubed is equal to 1000 decimeters cubed. So, 63 meters cubed is equal to 63,000 decimeters cubed.

Multiplying 63,000 decimeters cubed by 89 decimeters cubed gives us 5,607,000 decimeters cubed.

Finally, multiplying 5,607,000 decimeters cubed by 147 gives us 823,329,000 decimeters cubed.

Therefore, 63 м (в кубе) 89 дм (в кубе) * 147 = 823,329,000 дм (в кубе).

17 ч 48 мин + 12 ч 36 мин = ? To solve this, we need to add 17 hours and 48 minutes to 12 hours and 36 minutes.

Adding the hours together gives us 29 hours.

Adding the minutes together gives us 84 minutes. Since there are 60 minutes in an hour, we can convert 84 minutes to 1 hour and 24 minutes.

Therefore, 17 ч 48 мин + 12 ч 36 мин = 29 ч 24 мин.

8 лет 5 мес. + 12 лет 9 мес. = ? To solve this, we need to add 8 years and 5 months to 12 years and 9 months.

Adding the years together gives us 20 years.

Adding the months together gives us 14 months. Since there are 12 months in a year, we can convert 14 months to 1 year and 2 months.

Therefore, 8 лет 5 мес. + 12 лет 9 мес. = 20 лет 2 мес.
