\(\frac{5}{8}=\frac{5x125}{8x125}=\frac{625}{1000}=0,625\)

625/1000 bạn nha!

bằng 625

hộ em ạ em cần gấp

171/200 = 855/1000 = 0,855

855/1000 = 0,855

Đáp án C

5/8 = 5x125/8x125 = 625/1000

`48/10 = 24/5=4,8`

`213/10=213:10=21,3`

`3/1000=3:1000=0,003`

`25/1000 = 25:1000=0,025`

`647/100=647:100=6,47`

`982/100=982:100=9,82`

`385/10000=385:10000=0,0385`

`982/1000=0,982`
