Tìm một số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên trái 1 hàng ta được số B.Nếu chuyển dấu phẩy của nó sang bên phải một hàng ta được số C.Tổng của ba số A,B,C là 221,778.
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

Số A, B,C số nào nhỏ nhất
Đúng rồi số B
B kém A 10 lần
B kém C 100 lần
Tổng A+B+ C = 100XB+ B + 10XB = 111XB = 221,778
B= 1,998 sÔ A LÀ 19,98
