Explicație pas cu pas:
3 km + 15 hm = 300 dam + 150 dam = 450 dam
1 km = 10 hm = 100 dam
3 km x 100 = 300 dam
1 hm = 10 dam
15 hm x 10 = 150 dam
0,3 dam + 1,9 m = 30 dm + 19 dm = 49 dm
1 dam = 10 m = 100 dm
0,3 dam x 100 = 30 dm
1 m = 10 dm
1,9 m x 10 = 19 dm
7 km - 35 dam = 7000 m - 350 m = 6650 m
1 km = 10 hm = 100 dam = 1000 m
7 k m x 1000 = 7000 m
1 dam = 10 m
35 dam x 10 = 350 m
0,011 hm -1 m = 11 dm - 10 dm = 1 dm
1 hm = 10 dam = 100 m = 1000 dm
0,011 hm x 1000 = 11 dm
1 m = 10 dm
13 km + 11 hm = 1300 dam + 110 dam = 1410 dam
1 km = 10 hm = 100 dam
13 km x 100 = 1300 dam
1 hm = 10 dam
11 hm x 10 = 110 dam
3 dm +0,19 m = 300 mm + 190 mm = 490 mm
1 dm = 10 cm = 100 mm
3 dm x 100 = 300 mm
1 m = 10 dm = 100 cm = 1000 mm
0,19 m x 1000 = 190 mm
0,1 hm - 1 dam = 0,01 km - 0,01 km = 0 km
1 km = 10 hm
0,1 hm : 10 = 0,01 km
1 km = 10 hm = 100 dam
1 dam : 100 = 0,01 km
11 hm - 4,2 dam = 110000 cm - 4200 cm = 105800 cm
1 hm = 10 dam = 100 m = 1000 dm = 10000 cm
11 hm x 10000 = 110000 cm
1 dam = 10 m = 100 dm = 1000 cm
4,2 dam x 1000 = 4200 cm
13 mm + 150 cm = 0,0013 dam + 0,15 dam = 0,1513 dam
1 dam = 10 m = 100 dm = 1000 cm = 10000 mm
13 mm : 10000 = 0,0013 dam
1 dam = 10 m = 100 dm = 1000 cm
150 cm : 1000 = 0,15 dam
3 m + 19 cm = 30 dm + 1,9 dm = 31,9 dm
1 m = 10 dm
3 m x 10 = 30 dm
1 dm = 10 cm
19 cm : 10 = 1,9 dm
0,805 m - 3,5 dm= 0,00805 hm - 0,0035 hm = 0,00455 hm
1 hm = 10 dam = 100 m
0,805 m : 100 = 0,00805 hm
1 hm = 10 dam = 100 m = 1000 dm
3,5 dm : 1000 = 0,0035 hm
11 dm - 4 cm = 1100 mm - 40 mm = 1060 mm
1 dm = 10 cm = 100 mm
11 dm x 100 = 1100 mm
1 cm = 10 mm
4 cm x 10 = 40 mm
