hiệu số phần bằng nhau là

100 - 1 = 99 phần

số C là

957,231 : 99 x 1 = 9,669

số thập phân A là

9,669 x 10 = 96,69

Vì A chuyển sang  phải 1 hàng đc B suy ra B =10A <1>

    A chuyển sang trái đc C suy ra A = 10C <2>

Từ <1> , <2> suy ra  B=100C, vi 10x10=100

ta chuyển sang dạng toán hiệu tỉ : biết hiệu là 957,231 tỉ số C=1 phần , B = 100 phần 

vậy số C là :  957.231 : (100-1) = 9,669

vậy số thập phân A cần tìm là: 9.669 x 10 = 96,69

theo mình giải thế này thôi bạn nhớ tick nha, yên tâm mình thu lại đầy đủ rồi nha

19.98 đúng100%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

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

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
