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
Tìm một số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên trái một 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 158,895
Tìm một số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên trái một 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
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
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

Tìm một số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên trái một hàng ta được số B.Nếu chuyển dấu phẩy của nó sang bên phải một hàng ta được số C và C - B= 297,495
Tìm số thập phân A , biết chuyển dấu phẩy của nó sang phải một hàng ta được số B , chuyển dấu phẩy của A sang 2 hàng được số C và biết A + B +'C = 215,895
Tìm số thập phân A, biết rằng nếu chuyển dấu phẩy của nó sang bên trái một hàng ta được số B, chuyển dấu phẩy sang phải một hàng ta được số C. Tổng của A,B và C là 221,778
