cho 3 số thập phân a,b,c.Có tổng là 2004,0384.Tìm số a biết rằng nếu chuyển dấu phẩy của a sang bên trái 2 hàng ta được số b,nếu chuyển dấu phẩy của a sang bên phải 2 hàng thì ta được số c.: các bn giải hộ mk nha
Chuyển dấu phẩy của số A sang bên trái hai hàng ta được số B có nghĩa là số A gấp 100 lần số B.
Chuyển dấu phẩy của số A sang bên phải hai hàng ta được số C,có nghĩa là số C gấp 100 lần số A hay gấp 10 000 lần số B.
Gọi số B là một phần thì số A là 100 phần và số C là 10 000 phần .
Tổng số phần bằng nhau là : 10 000 + 100 + 1 = 10 101 ( phần )
Số B là : 2004,0384 : 10 101 = 0,1984
Số A là : 0,1984 x 100 = 19,84
Đáp số: 19,84

Cho 3 số thập phân A , B , C có tổng là 221 ,778 Tìm số a biết rằng nếu chuyển dấu phẩy của A sang bên trái một hàng thì được số B nếu chuyển dấu phẩy của A sang bên phải một hàng thì được số C
Nếu chuyển dấu phẩy của số thập phân A sang bên trái một hàng ta được số B
=> A x 0,1 = B
Chuyển dấu phấy của nó sang phải một hàng ta được số C
=> A x 10 = C
A + B + C = 221,778
A + A x 0,1 + A x 10 = 221,778
A x 11,1 = 221,778
A = 221,778 : 11,1 = 19,98
