2 Jawaban

  • 1.) 860 dm + 200 cm = .....cm
    Jawab :
    - 860 dm = 8.600 cm
    - 200 cm
    Jadi, 860 dm + 200 cm = 8.800 cm

    2.) 8 km + 9000 m =......km
    Jawab :
    - 8 km
    - 9.000 m = 9 km
    Jadi, 8 km + 9000 m = 17 km

    3.) 90 dm + 500 cm = ..... dm
    Jawab :
    - 90 dm
    - 500 cm = 50 dm
    Jadi, 90 dm + 500 cm = 140 dm

    4.) 800 dm + 3600 cm =......m
    Jawab :
    - 800 dm = 80 m
    - 3.600 cm = 36 m
    Maka, 800 dm + 3600 cm = 116 m

    5.) 5 km + 8000 dm = ......m
    Jawab :
    - 5 km = 5.000 m
    - 8.000 dm = 800 m
    Jadi, 5 km + 8000 dm = 5.800 m

    6.) 5.500 cm + 3500 dm =.....m
    Jawab :
    - 5.500 cm = 55 m
    - 3.500 dm = 350 m
    Jadi, 5.500 cm + 3500 dm = 405 m

    7.) 850 cm + 70 dm = .....cm
    Jawab :
    - 850 cm
    - 70 dm = 700 cm
    Jadi, 850 cm + 70 dm = 1.550 cm
  • 1. Dik = 860 dm × 10 = 8600 cm
    200 cm
    8600 + 200 = 8800 cm
    2. Dik = 8 km
    9000 m : 1000 = 9 km
    JB = 8 + 9 = 17 km
    3. 90 dm
    500 cm : 10 = 50 dm
    90 + 50 = 140 dm
    4. 800 dm : 10 = 80 m
    3600 cm : 100 = 36 m
    Jb = 80 + 36 = 116 m
    5. 5 km × 1000 = 5000 m
    8000 dm : 10 = 800 m
    5000 + 800 = 5800 m
    6. 5.500 : 100 = 55 m
    3500 dm : 10 = 35 m
    55 + 35 = 90 m
    7. 850 cm
    70 dm × 100 = 700 cm
    JB = 850 cm + 700 cm = 1750 cm

    Semoga Benar dan membantu!
