Answer 2

А) 44м5см меньше 440дм5см To compare the two lengths, we need to convert both measurements to the same unit. Let's convert them to centimeters since both meters and centimeters are used in the given measurements.

44m 5cm is equal to 4405cm. 440dm 5cm is equal to 44050cm.

So, 44050cm is greater than 4405cm. Therefore, the statement "44м5см меньше 440дм5см" (44m5cm is smaller than 440dm5cm) is incorrect.

Б) 5400кг меньше 5т4кг To compare the two masses, we need to convert them to the same unit. Let's convert them to kilograms since both kilograms and metric tons (t) are used in the given measurements.

5t 4kg is equal to 5400kg.

So, 5400kg is equal to 5400kg. Therefore, the statement "5400кг меньше 5т4кг" (5400kg is smaller than 5t4kg) is correct.

В) 6ч54 = 414мин To convert hours to minutes, we need to multiply the number of hours by 60 (since there are 60 minutes in an hour) and then add the number of minutes.

6 hours 54 minutes is equal to (6 * 60) + 54 = 414 minutes.

So, 6ч54 equals 414 minutes. Therefore, the statement "6ч54 = 414мин" (6 hours 54 minutes is equal to 414 minutes) is correct.

Г) 60дм7см больше чем 6м7дм To compare the two lengths, we need to convert them to the same unit. Let's convert them to centimeters since both meters and centimeters are used in the given measurements.

60dm 7cm is equal to 607cm. 6m 7dm is equal to (6 * 100) + (7 * 10) = 670cm.

So, 607cm is smaller than 670cm. Therefore, the statement "60дм7см больше чем 6м7дм" (60dm7cm is greater than 6m7dm) is incorrect.

In summary: - Statement А) 44м5см меньше 440дм5см is incorrect. - Statement Б) 5400кг меньше 5т4кг is correct. - Statement В) 6ч54 = 414мин is correct. - Statement Г) 60дм7см больше чем 6м7дм is incorrect.

So, the correct statements are Б) 5400кг меньше 5т4кг and В) 6ч54 = 414мин.
