Question

4 м 40 мм = ... см 8дм 6 см = MM ... 2 сут. 3 ч = ... ч 175 мин - Ч ... МИН ...​

Answer 1

3ч=180мин
174мин=2ч 54мин

Answer 2

4 м + 40 мм = ... см

To convert 4 meters and 40 millimeters to centimeters, we need to convert each unit to the same base unit, which is centimeters.

1 meter is equal to 100 centimeters, and 1 millimeter is equal to 0.1 centimeters.

So, 4 meters is equal to 4 * 100 = 400 centimeters.

And 40 millimeters is equal to 40 * 0.1 = 4 centimeters.

Therefore, 4 meters and 40 millimeters is equal to 400 centimeters + 4 centimeters, which is 404 centimeters.

8 дм + 6 см = ... мм

To convert 8 decimeters and 6 centimeters to millimeters, we need to convert each unit to the same base unit, which is millimeters.

1 decimeter is equal to 10 centimeters, and 1 centimeter is equal to 10 millimeters.

So, 8 decimeters is equal to 8 * 10 = 80 centimeters.

And 6 centimeters is equal to 6 * 10 = 60 millimeters.

Therefore, 8 decimeters and 6 centimeters is equal to 80 centimeters + 60 millimeters, which is 140 millimeters.

2 сут. + 3 ч = ... ч

To add 2 days and 3 hours, we need to convert each unit to the same base unit, which is hours.

1 day is equal to 24 hours.

So, 2 days is equal to 2 * 24 = 48 hours.

Therefore, 2 days and 3 hours is equal to 48 hours + 3 hours, which is 51 hours.

175 мин - Ч = ... МИН

To subtract an unknown number of hours (Ч) from 175 minutes, we need to convert the hours to minutes.

1 hour is equal to 60 minutes.

So, Ч hours is equal to Ч * 60 minutes.

Therefore, 175 minutes - Ч * 60 minutes is equal to 175 - Ч * 60 minutes.

Unfortunately, without knowing the value of Ч, we cannot determine the exact result.
