650 m-1 500 dm = ? cm
8 km - 8 hm = ? dam​

Answer 1

a) 6 dam + 23 m=? m

60m+23m=83m

12 km + 15 dam = ? m

12000+150m=12150m

12 hm + 63 dam = ? m

1200m+630m=1830m

19 hm + 55 dam = ? m

1900m+550m=2450m

192 m + 208 m = ? dam

19,2dam+20,8dam=40dam

20 dm + 32 cm = ? mm

2000mm+320mm=2320mm

b) 64 km - 22 dam = ? m

64000m-220m= 63780m

750 cm - 120 mm = ? mm

7500mm-120mm=7380mm

32 km - 21 dam = ? dam

3200dam-21dam=3179dam

1 m- 15 cm = ? cm

100cm -15cm=85cm

650 m-1 500 dm = ? cm

65000cm-15000cm=50000cm

8 km - 8 hm = ? dam

800dam-80dam=720dam
