Sửa: 18hm²217m²=18,0217hm²

Answer 2

25m7dm = \(\dfrac{257}{10}\)m 

4dm6cm = \(\dfrac{46}{100}\)m

 15dm5mm= \(\dfrac{1505}{1000}\) dm 

18m2cm = \(\dfrac{1802}{100}\)m 

2dam25m2= \(\dfrac{225}{100}\)dam2 

1km25dam2 = \(\dfrac{1002}{1000}\)km2

6hm27dam2= \(\dfrac{607}{100}\)hm2

18hm217m2= \(\dfrac{18017}{1000}\)hm2
