1 ) 14 hm + 6 dam - 60 dam = ? m
14 hm = 1400 m
6 dam = 60 m
60 dam = 600 m
1400 m + 60 m - 600 m =
= 1460 m - 600 m
= 860 m
2 ) 15000 mm - 500 cm + 60 dm = ? m
15000 mm = 15 m
500 cm = 5 m
60 dm = 6 m
15 m - 5 m + 6 m =
= 10 m + 6 m
= 16 m
3 ) 14700 m - 1300 dam + 750 hm = ? km
14700 m = 14,7 km
1300 dam = 13 km
750 hm = 75 km
14,7 km - 13 km + 75 km =
= 1,7 km + 75 km
= 76,7 km
