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 

2004,0384:101,01=19,84

đúng thì cho nha

de qua

Giải giúp mk đi

19, 84 nha ban

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

Giải:

Dịch dấu phẩy của số A sang trái ta được số B bằng:

1 : 10 = 1/10 (số A)

Dịch dấu phẩy của số A sang phải một hàng ta được số C bằng:

1 x 10 = 10 (lần số A)

Số A là:

221,778 : (1 + 1/10 + 10) = 19,98

Đáp số:..

Giải:

Số B bằng: 1 x 10 = 10/1 (số A)

Số C bằng: 1 : 10 = 1/10 (số A)

Số A bằng: 241,314:(1+ 10 + 1/10) = 21,74

Đáp số:.
