nếu chuyển dấu phẩy của số A sang bên trái một hàng ta được số B thì B=\(A\cdot\frac{1}{10}\)

nếu chuyển dấu phẩy của số A sang bên phải một hàng ta được số C thì C=\(A\cdot10\)

TA có

A+B+C=\(289,264\)

\(A+A\cdot\frac{1}{10}+A\cdot10\)=\(289,264\)

\(A\cdot1+A\cdot\frac{1}{10}+A\cdot10=289,264\)

\(A\cdot\left(1+\frac{1}{10}+10\right)=289,264\)

\(A\cdot\left(1+0,1+10\right)=289,264\)

\(A\cdot\left(1,1+10\right)\)\(=289,264\)

\(A\cdot11,1=289,264\)

\(A=289,264:11,1\)

\(A=...\)

\(V\)ậy A=...

k mk nhé bạn

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

chuyển dấu phẩy sang trái 1 hàng thì A gấp B 10 lần

Chuyển dấu phẩy sang phải 1 lần thì C gấp B 10 lần

Vậy C gấp B 100 lần

Gọi B = 1 lần, C = 100 lần

Tìm B, ta lấy:

289,264 : (100 + 1) = 2,864

vì B kém A 10 lần nên A = 2,864 x 10 = 28,64

vậy A = 28,64

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
