1. 9dm3 + 7 cm3= mm3 2. 20 dal + 500 dl= cl 3. 12 dl= cc 4. 56000 cm3= l 5. 35 dl= mm3 6. 4 dm3 + 250 cm3= cm3 7. 400 l - 15 dl = l 8. 50

1.970mm3 2.25000cl 3.1 20cc 4.56l 5.3. 500.000.000

1. 9 dm3 = 9.100000 = 9.000.000 mm3
7 cm3 = 7.1000 = 7000 mm3
9.000.000 + 7000 = 9.007.000 mm3
2. 20 dl = 20.10 = 200 cl
500 dl = 500.10 = 5000 cl
200 + 5000 = 5200 cl
3. catatan : 1 cm3 = 1 ml = 1 cc
jadi dl ubah menjadi ml
12 dl = 12.100 = 1200 cc
4. catatan : 1 m3 = 1 kl = 1000 l
jadi tinggal di bagi 1000 = 56000 : 1000 = 56 l
5. 35 dl = 35.10 = 350 ml/cm3
350.1000 = 350000 mm4
6. 4 dm3 = 4.1000 = 4000 cm3
250 cm3 = 250.1 = 250 cm3
4000+250 = 4250 cm3
7. 400 l = 400.1 = 400 l
15 dl = 15:10 = 1,5 l
400 - 1,5 = 398,5
8. kalo ini Aq ga tau soalnya ga ada satuannya maaf :-)
9. 35 ml = 35.1 = 35 ml
35-35=0 cm3
10. 28000000 m3 = 28000000 : 1000 = 28000
Maaf kalo jawabannya salah
semoga membantu :-)
