Cho ba số thập phân A,B,C có ổng là 2004,0384. Tìm số A biết rằng nếu chuyển dấu phẩy của số A sang bên trái hai hàng ta được số B. Nếu chuyển dấu phẩy của số A sang phải hai hàng ta được số C..
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
Đúng 0

Ta thấy trong 3 số thì số B là nhỏ nhất
B kém A 10 lần
B kém C 100 lần
Tổng A+B+ C = 100 x B+ B + 10 x B = 111 x B = 221,778
B= 1,998 nên số A là 19,98
số C là: 199,8
