Tick đúng cho mình nhé

1/25 và 5/8 thế thôi bạn nha

5/8 và 1/25

k đi

CHÚC BẠN HỌC GIỎI

Viết các số sau dưới dạng phân số thập phân : 

a ) 0,7 = 7/10 ; 0,94 = 94/100 ; 2,7 = 27/10 ; 4,567 = 4567/1000

b ) 1/4 = 25/100; 7/5 = 14/10 ; 16/25 = 64/100 ; 3/2 = 15/10 

Tk ủng hộ mk nha ạ! cảm ơn nhiều ........
