Kasi tau jawabannya kakak pintar 1-10

1.47 m = ___ cm
   47 m = 47 x ( 10x10x10)
        = 47 x 1000
        = 47.000 cm
2. 200 dam = ____ m
    200 dam = 200 x 10
                 = 2.000 m
3. 40.000 m = ___ km
    40.000 m = 40.000 : ( 10x10x10)
                  = 40.000 :1000
                  = 40 km
4. 30 dm = ___ mm
              = 30 x (10×10)
              = 30 X 100 = 3.000
5. 25.000 cm = ___ m
                    = 25.000 : (10x10x10)
                    = 25.000 : 1000 = 25 m
6. 40 dm + 80 mm =     cm
    40 dm = 40 x 10 = 400 cm
    80 mm = 80 : 10 = 8 cm
    400 cm + 8 cm += 408 cm
7. 7000 m + 120 hm = ….. km
    7000 m = 7000 : 1000 = 7 km
    120 hm = 120 : 10 = 12 km
     7 km + 12 km + = 19 km
8. 18 m + 100 dm – 48 cm =    cm
    18 m = 18 x 100.000 = 1.800.000 cm
    100 dm = 100 x 10 = 1.000 cm
     48 cm 
     1.800.000 + 1000 – 48 = 1.800.952
9. 

1. 47 m= 4700 cm
2. 200 dam= 2000 m
3. 40.000 m= 40 km
4. 30 dm= 3000 mm
5. 25.000 cm = 25 m
6. 40 dm + 80 mm
=400 cm + 8 cm
=408 cm
7. 7.000 m + 120 hm
=7 km + 12 km
= 19 km
8. 45 dam – 120 dm
=450.000 mm – 12.000 mm
=438.000 mm
9. 18 m + 100 dm – 48 cm
= 1800 cm + 1000 cm – 48 cm
= 2.752 cm
10. 5 km – 415 m – 8.000 cm
= 5000 m – 415 m- 80 m
= 4.505 m
