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

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.

Tìm số thập phân A biết rằng nếu chuyển dấu phẩy của nó sang bên phải một hàng ta được số B. Chuyển dấy phẩy sang bên trái 1 hàng ta được số C. Biết B-C=957,231
trả lời nhanh giùm tớ nha
Ta thấy : B = A * 10 và C = A * 0,1
Mà B - C = 957,231 nên A * 10 - A * 0,1 = 957,231
=> A * 9,9 = 957,231
=> A = 96,69
Đ/s : 96,69
