Answer 2

To solve the given equations:

1. 7 hours 20 minutes - 2 hours 30 minutes: To subtract the given times, we need to convert them to a common unit (minutes): 7 hours 20 minutes = (7 * 60) + 20 = 440 minutes 2 hours 30 minutes = (2 * 60) + 30 = 150 minutes Now, subtracting the minutes: 440 - 150 = 290 minutes

   Therefore, 7 hours 20 minutes - 2 hours 30 minutes = 290 minutes.

2. 5 tons 4 centners + 350 kilograms: Since there are 100 centners in a ton, we can convert 5 tons to centners: 5 tons = 5 * 100 centners = 500 centners

   Now, adding the centners and kilograms: 500 centners + 350 kilograms

   Since there are 100 kilograms in a centner, we need to convert the centners to kilograms: 500 centners = 500 * 100 kilograms = 50,000 kilograms

   Now we can add the kilograms: 50,000 kilograms + 350 kilograms = 50,350 kilograms.

   Therefore, 5 tons 4 centners + 350 kilograms = 50,350 kilograms.

3. 2 hectares + 2000 square meters: Since there are 10,000 square meters in a hectare, we can convert 2 hectares to square meters: 2 hectares = 2 * 10,000 square meters = 20,000 square meters

   Now, adding the square meters: 20,000 square meters + 2000 square meters = 22,000 square meters.

   Therefore, 2 hectares + 2000 square meters = 22,000 square meters.

4. 3 cubic centimeters - 2 cubic millimeters: Since there are 1000 cubic millimeters in a cubic centimeter, we can convert the cubic centimeters to cubic millimeters: 3 cubic centimeters = 3 * 1000 cubic millimeters = 3000 cubic millimeters

   Now, subtracting the cubic millimeters: 3000 cubic millimeters - 2 cubic millimeters = 2998 cubic millimeters.

   Therefore, 3 cubic centimeters - 2 cubic millimeters = 2998 cubic millimeters.
