Jawaban:

1. 12 km + 25hm = 1450 dam

2. 25 km - 10 dm = 24.999 m

3. 8 dam - 150 dm = 70.000 mm

4. 45 dam + 650 mm = 45.065 cm

5. 4580 km - 1500 dam = 4565 km

6. 25 m + 150 dm - 170 cm = 383 dm

7. 6 km - 12 hm - 3 dam = 477 dam

8. 75 km - 15 hm - 1750 m = 71.750 m

Penjelasannya:

1. 12 km + 25 hm = ... dam

jawab =

- 12 km × 100 = 1200 dam

- 25 hm × 10 = 250 dam

Jadi 1200 - 250 = 1450 dam

2. 25 km - 10 dm = ... m

jawab =

- 25 km × 1000 = 25.000 m

- 10 dm : 10 = 1 m

Jadi 25.000 - 1 = 24.999 m

3. 8 dam - 150 dm = ... mm

jawab =

- 8 dam × 10000 = 80.000 mm

- 150 dm × 1000 = 150.000 mm

Jadi 150.000 - 80.000 = 70.000 mm

4. 45 dam + 650 mm = ... cm

jawab =

- 45 dam × 1000 = 45.000 cm

- 650 mm : 10 = 65 cm

Jadi 45.000 - 65 = 45.065 cm

5. 4580 km - 1500 dam = ... km

jawab =

- 4580 km × 1 = 4580 km

- 1500 dam : 100 = 15 km

Jadi, 4580 - 15 = 4.565 km

6. 25 m + 150 dm - 170 cm = ... dm

jawab =

- 25 m × 10 = 250 dm

- 150 dm × 1 = 150 dm

- 170 cm : 10 = 17 dm

Jadi 250 + 150 = 400 dm - 17 dm = 383 dm

7. 6 km - 12 hm - 3 dam = ... dam

jawab =

- 6 km × 100 = 600 dam

- 12 hm × 10 = 120 dam

- 3 dam × 1 = 3 dam

Jadi 600 - 120 - 3 = 477 dam

8. 75 km - 15 hm - 1750 m = ... m

jawab =

- 75 km × 1000 = 75.000 m

- 15 hm × 100 = 1.500 m

- 1750 m × 1 = 1.750 m

Jadi 75.000 - 1.500 - 1.750 = 71.750 m
