Question

Уточни результат сравнения величин. 1) 54км/ч > 12м/мин (на ) 2) 130дет./ч > 2 дет./мин (на ) 3) 72 км./ч > 5 м/сек (в ) 4) 40руб./ц > 20 руб./т (в ) 5) 2 стр./мин > 1 стр./ч (в ) И нужен пример

Answer 1

1) 54 км/ч = 15 м/с = 900 м/мин
     900 м/мин > 12 м/мин на:   900 - 12 = 888 (м/мин)

2) 130 дет./ч = 2 1/6 дет./мин
     2 1/6 дет./мин > 2 дет./мин  на:   2 1/6 - 2 = 1/6 (дет./мин)

3) 72 км/ч = 72 : 3,6 = 20 (м/c)
     20м/c > 5 м/с   в: 20 : 5 = 4 (раза)

4)  40 руб./ц = 400 руб./т
     400 руб./т > 20 руб./т  в:  400 : 20 = 20 (раз)

5)  2 стр./мин = 120 стр./ч
     120 стр./ч > 1 стр./ч  в: 120 : 1 = 120 (раз)

Answer 2

Result of Comparing Values:

1) 54 km/h > 12 m/min 2) 130 det./h > 2 det./min 3) 72 km/h > 5 m/sec 4) 40 rub./centner > 20 rub./ton 5) 2 pages/min > 1 page/hour

Let's go through each comparison and provide an example to illustrate the result.

1) 54 km/h > 12 m/min: To compare these values, we need to convert them to the same unit. Let's convert 54 km/h to m/min. Since 1 km = 1000 m and 1 hour = 60 minutes, we can calculate: 54 km/h = 54,000 m/h = 900 m/min

Now we can compare 900 m/min with 12 m/min. It is clear that 900 m/min is greater than 12 m/min.

Example: Imagine two cars racing. Car A is traveling at a speed of 54 km/h, while Car B is moving at a speed of 12 m/min. In this scenario, Car A is moving faster than Car B.

2) 130 det./h > 2 det./min: To compare these values, we need to convert them to the same unit. Let's convert 130 det./h to det./min. Since 1 hour = 60 minutes, we can calculate: 130 det./h = 130 det./60 min = 2.17 det./min (rounded to two decimal places)

Now we can compare 2.17 det./min with 2 det./min. It is clear that 2.17 det./min is greater than 2 det./min.

Example: Let's say we have two factories producing toys. Factory A produces 130 toys per hour, while Factory B produces 2 toys per minute. In this case, Factory A is producing toys at a higher rate than Factory B.

3) 72 km/h > 5 m/sec: To compare these values, we need to convert them to the same unit. Let's convert 72 km/h to m/sec. Since 1 km = 1000 m and 1 hour = 3600 seconds, we can calculate: 72 km/h = 72,000 m/3600 s = 20 m/s

Now we can compare 20 m/s with 5 m/s. It is clear that 20 m/s is greater than 5 m/s.

Example: Consider two athletes running. Athlete A is running at a speed of 72 km/h, while Athlete B is running at a speed of 5 m/s. In this scenario, Athlete A is running faster than Athlete B.

4) 40 rub./centner > 20 rub./ton: To compare these values, we need to convert them to the same unit. Let's convert 40 rub./centner to rub./ton. Since 1 centner = 100 kg and 1 ton = 1000 kg, we can calculate: 40 rub./centner = 40 rub./100 kg = 0.4 rub./kg 20 rub./ton = 20 rub./1000 kg = 0.02 rub./kg

Now we can compare 0.4 rub./kg with 0.02 rub./kg. It is clear that 0.4 rub./kg is greater than 0.02 rub./kg.

Example: Suppose we are comparing the prices of wheat. Wheat A is priced at 40 rubles per centner, while Wheat B is priced at 20 rubles per ton. In this case, Wheat A is more expensive than Wheat B.

5) 2 pages/min > 1 page/hour: To compare these values, we need to convert them to the same unit. Let's convert 2 pages/min to pages/hour. Since 1 hour = 60 minutes, we can calculate: 2 pages/min = 2 pages/60 min = 0.0333 pages/hour (rounded to four decimal places)

Now we can compare 0.0333 pages/hour with 1 page/hour. It is clear that 1 page/hour is less than 0.0333 pages/hour.

Example: Consider two printers. Printer A can print 2 pages per minute, while Printer B can print 1 page per hour. In this scenario, Printer A is more efficient than Printer B in terms of printing speed.

I hope these examples help clarify the results of the comparisons. Let me know if you have any further questions!
