Vì chuyển dấu phẩy của số đó sang bên phải một hàng ta được số A nên số A bằng 10 lần số đã cho.

Vì dời dấu phẩy của số đó sang trái một hàng ta được số B nên số B bằng:     \(\dfrac{1}{10}\) số đã cho

Tỉ  số của số B và số A là:

      \(\dfrac{1}{10}\) : 10 = \(\dfrac{1}{100}\)

Ta có sơ đồ:

        

Theo sơ đồ ta có: 

Số B là: 244,332 : (100 - 1) = 2,468

Số đã cho là : 2,468 x 10 = 24,68

Đáp số:...

Vì dời dấu phẩy của số đó sang trái một hàng ta được số B nên số B bằng:     110 số đã cho

Tỉ  số của số B và số A là:

      110 : 10 = 1100
 

Số B là: 244,332 : (100 - 1) = 2,468

Số đã cho là : 2,468 x 10 = 24,68

Vì chuyển dấu phẩy của số đó sang bên phải một hàng ta được số A nên số A bằng \(10\) lần số đã cho

Vì dời dấu phẩy của số đó sang trái một hàng ta được số \(B\) nên số \(B\) bằng \(\dfrac{1}{10}\)số đã cho

Tỉ số giữa số \(B\) và số \(A\) là:

\(\dfrac{1}{10}:10=\dfrac{1}{100}\)

Số \(B\) là:

\(244,332:\left(100-1\right)=2,468\)

Số đã cho là:

\(2,468.10=24,68\)

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

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
