1)8дм 1см - 5дм 6см2)5год 25хв - 2год 48хв​

Answer 1

1) 8дм 1 см - 5дм 6см = 81 - 56 = 25см = 2дм 5см

2) 5год 25хв - 2год 48хв = 325 - 168 = 157хв = 2год 37хв

Answer 2

1. To subtract these measurements, we need to align the units. Let's convert everything to centimeters for easier calculations.

8 dm 1 cm = (8 * 10) cm + 1 cm = 81 cm 5 dm 6 cm = (5 * 10) cm + 6 cm = 56 cm

Now, subtract the second measurement from the first: 81 cm - 56 cm = 25 cm

Therefore, 8 dm 1 cm - 5 dm 6 cm is equal to 25 cm.

2. Similarly, let's convert the measurements to minutes for easier calculations.

5 hours 25 minutes = (5 * 60) minutes + 25 minutes = 325 minutes 2 hours 48 minutes = (2 * 60) minutes + 48 minutes = 168 minutes

Now, subtract the second measurement from the first: 325 minutes - 168 minutes = 157 minutes

Therefore, 5 hours 25 minutes - 2 hours 48 minutes is equal to 157 minutes.
