Question

Calculati:
3 km + 15 hm = ?dam
0,3 dam + 1,9 m = ?dm
7 km - 35 dam = ?m
0,011 hm - 1 m = ?dm
13 km + 11 hm = ?dam
3 dm + 0,19 m = ?mm
0,1 hm - 1 dam = ?km
11 hm - 4,2 dam = ?cm
13 mm - 150 cm = ?dam
3 m + 19 cm = ?dm
0,805 m - 3,5 dm = ?hm
11 dm - 4 cm = ?mm

Answer 1

3 km + 15 hm = ?dam
3 km = 300 dam
15 hm = 150 dam
300 dam + 150 dam = 450 dam


0,3 dam + 1,9 m = ?dm
0,3 dam = 300 dm
1,9 m = 19 dm
300 dm + 19 dm = 319 dm


7 km - 35 dam = ?m
7 km = 7000 m
35 dam = 350 m
7000 m - 350 m = 6650 m


0,011 hm - 1 m = ?dm
0,011 hm = 11 dm
1 m = 10 dm
11 dm - 10 dm = 1 dm


13 km + 11 hm = ?dam
13 km = 1300 dam
11 hm = 110 dam
1300 dam + 110 dam = 1410 dam


3 dm + 0,19 m = ?mm
3 dm = 300 mm
0,19 m = 190 mm
300 mm + 190 mm = 490 mm


0,1 hm - 1 dam = ?km
0,1 hm = 0,01 km
1 dam = 0,01 km
0,01 km - 0,01 km = 0 km


11 hm - 4,2 dam = ?cm
11 hm = 110 000 cm
4,2 dam =4 200 cm
110 000 cm - 4 200 cm = 105 800 cm


13 mm - 150 cm = ?dam
13 mm = 0,0013 dam
150 cm = 0,150 dam
0,0013 dam - 0,150 dam = - 0,1487 dam


3 m + 19 cm = ?dm
3 m = 30 dm
19 cm = 1,9 dm
30 dm + 1,9 dm =31,9 dm


0,805 m - 3,5 dm = ?hm
0,805 m = 0,00805 hm
3,5 dm = 0,035 hm
0,00805 hm - 0,035 hm = - 0,02695 hm


11 dm - 4 cm = ?mm
11 dm = 1100 mm
4 cm = 40 mm
1100 mm - 40 mm = 1060 mm
