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 A,B,C là 221,778
cho cả cách làm nhé
B kém A 10 lần
B kém C 100 lần
A 10 phần ; C 100 phần ; B 1 phần
tổng số phần bằng nhau : 100 + 10 + 1 = 111 phần
số thập phân A là : 221,778 : 111 x 10 = 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 = 100 x B + 10 x B = 111 x B = 221,778
B= 1,998 Số A là 19,98

cho số thập phân A, nếu dịch chuyển dấu phẩy của số A sang phải 1 hàng ta được số B, dịch chuyển sang bên trái 1 hàng ta được số C. Biết B-C= 447,48. Tìm số A
số B 100 phần
số A 10 phần
số C :1 phần
số C là
447,48 : (100-1) = 4,52
số A là
4,52 x 10 = 45,2

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
ai nhanh mk k 3 cái
vì nếu chuyển dấu phẩy của nó sang bên trái 1 hàng thì số đó giảm đi 10 là
và: nếu chuyển dấu phẩy của nó sang bên phải 1 hàng thì số đó tăng thêm 10 lần.
ta có sơ đồ: ( bạn tự vẽ nha, số A là 10 phần, số B là 1 phần và số C là 100 phần )
tổng số phần bằng nhau là: 1+10+100=111(phần)
số A là: 221,778 : 111 x 10 = 19,98
đáp số: 19,98.
