Ax100=B 
A+B=1854,36
<=> A+100A=1854,36
=> A = 1854,36:101
 => A = 18.36
      B= 1836

11 tháng 12 2022

   Chuyển dấu phẩy sang bên phải 2 hàng thì số đó tăng 100 lần: \(B=100\times A\)

   Tổng hai số là \(A+B=1854,36\)

                      \(\Rightarrow A+100\times A=1854,36\)

                       \(\Rightarrow101A=1854,36\)

                       \(\Rightarrow A=18,36\)

đợi mình chút 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 = 100XB+ B + 10XB = 111XB = 221,778

B= 1,998 sÔ A LÀ 19,98

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
