$\text{10cm = 10 : 10 = 1dm}$ $\text{100cm = 100 : 10 = 10dm}$ $\text{10dm = 10 : 10 = 1m}$ $\text{10000m = 10000 : 1000 = 10km}$ $\text{230cm = 230 : 10 = 23dm}$ $\text{400km = 400 × 1000 = 400000m}$ Trả lời
10 cm = 1 dm => 1 dm = 10 cm => 1 cm = 0,1 dm ———– 100 cm = 10 dm => 1 dm = 10 cm => 10 cm = 0,1 dm ———– 10 dm = 1 m => 1 m = 10 dm => 10 dm = 1 m ———– 10000 m = 10 km => 1 km = 1000 m => 1 m = 0,001 km ———– 230 cm = 23 dm => 1 dm = 10 cm => 1 cm = 0,1 dm ———– 400 km = 400000 m => 1 km = 1000 m => 1 m = 0,001 km $# ????????????????????$ Trả lời
