tk ủng hộ mk nha m.n!

a) 1m = 10dm = 100cm = 1000mm           b) 1m = \(\dfrac{1}{10}\)dam = 0,1dam 

1km = 1000m                                            1m = \(\dfrac{1}{1000}\)km = 0,001km

1kg = 1000g                                              1g = \(\dfrac{1}{1000}\)kg = 0,001kg

1 tấn = 1000kg                                          1kg = \(\dfrac{1}{1000}\) tấn = 0,001 tấn.

Viết (theo mẫu):
