Answer 2

Let's perform the calculations step by step:

1. Add 12 cm 8 mm and 5 cm 8 mm: 12 cm + 5 cm = 17 cm 8 mm + 8 mm = 16 mm

   Combine the results: 17 cm 16 mm

2. Subtract 4 cm 70 cm from 9 cm 50 cm: 9 cm - 4 cm = 5 cm 50 cm - 70 cm = -20 cm (note: we get a negative value here, which means we borrow from the whole part)

   Combine the results: 5 cm 30 cm (since 30 cm is equivalent to 1 whole cm, we add it back to the 5 cm)

3. Add 20 km 400 m and 16 km 900 m: 20 km + 16 km = 36 km 400 m + 900 m = 1300 m (note: 1000 m is equivalent to 1 km)

   Combine the results: 36 km 1300 m (since 1300 m is equivalent to 1 km 300 m, we add it back to the 36 km)

4. Subtract 10 kg 200 g from 32 kg 500 g: 32 kg - 10 kg = 22 kg 500 g - 200 g = 300 g (note: 1000 g is equivalent to 1 kg)

   Combine the results: 22 kg 300 g (since 300 g is equivalent to 0.3 kg, we add it back to the 22 kg)

Final results:

1. 12 cm 8 mm + 5 cm 8 mm = 17 cm 16 mm
2. 9 cm 50 cm - 4 cm 70 cm = 5 cm 30 cm
3. 20 km 400 m + 16 km 900 m = 36 km 1300 m
4. 32 kg 500 g - 10 kg 200 g = 22 kg 300 g
