4. Вырази в указанных единицах измерения. 1 ч 20 мин90 минминмин6 дм 8 см14 дмCSІ18 см -800 кгM 2 класс помогите​

Answer 1

1 ч = 60 мин.
1 ч 20 мин. = 1 * 60 + 20 = 60 + 20 = 80 мин.
90 мин. = 60 мин. + 30 мин. = 1 ч + 30 мин. = 1 ч 30 мин.
1 дм = 10 см
6 дм 8 см = 6 * 10 + 8 = 60 + 8 = 68 см
1 м = 10 дм
14 дм = 10 дм + 4 дм = 1 м + 4 дм = 1 м 4 дм
1 дм = 10 см
18 см = 10 см + 8 см = 1 дм + 8 см = 1 дм 8 см
1 ц = 100 кг
800 кг = 800 : 100 = 8 ц

Answer 2

Express the following measurements in the specified units:

1. 1 hour 20 minutes in minutes: - To convert hours to minutes, multiply by 60. - 1 hour * 60 minutes/hour = 60 minutes - 20 minutes + 60 minutes = 80 minutes [[1]]

2. 90 minutes in hours and minutes: - To convert minutes to hours, divide by 60. - 90 minutes / 60 minutes/hour = 1 hour - The remainder is the number of minutes: 90 minutes % 60 minutes/hour = 30 minutes [[2]]

3. 6 decimeters (dm) 8 centimeters (cm) in centimeters: - 1 decimeter = 10 centimeters - 6 decimeters * 10 centimeters/decimeter = 60 centimeters - 60 centimeters + 8 centimeters = 68 centimeters [[3]]

4. 14 decimeters (dm) in centimeters: - 1 decimeter = 10 centimeters - 14 decimeters * 10 centimeters/decimeter = 140 centimeters [[4]]

5. CSІ 18 centimeters in meters: - There is no specific conversion factor for "CSІ" mentioned in the question. If you meant "cm" instead of "CSІ," then: - 18 centimeters * 1 meter/100 centimeters = 0.18 meters [[5]]

6. -800 kilograms (kg) in grams: - 1 kilogram = 1000 grams - -800 kilograms * 1000 grams/kilogram = -800,000 grams [[6]]

7. M 2 class: - It is unclear what "M 2 class" refers to. Could you please provide more context or clarify the question?

I hope this helps! Let me know if you have any further questions.
