1) 6200m=? hm=? km
1 hm = 100 m
1 km = 1000 m
6200 m = 6200 : 100 = 62 hm
6200 m = 6200 : 1000 = 6,2 km
2) 12,03cm=? mm =? m
1 cm = 10 mm
1 cm = 1 : 100 = 0,01 m
12,03 cm = 12,03 x 10 = 120,3 mm
12,03 cm = 12,03 : 100 = 0,1203 m
3) 0,014 dam =? cm =? m
1 dam = 10 m = 1000 cm
0,014 dam = 0,014 x 1000 = 14 cm
0,014 dam = 0,014 x 10 = 0,14 m
4) 224m=? mm =? km
1 m = 1000 mm
1 m = 1 : 1000 = 0,001 km
224 m = 224 x 1000 = 224 000 mm
224 m = 224 : 1000 = 0,224 km
