Trong ba số A.B,C  số B nhỏ nhất

B kém A 10 lần

B kém C 100 lần 

Tổng A+B+ C = 100XB+ B + 10XB = 111XB = 221,778

số A LÀ 19,98

Nếu chuyển dấu phẩy của số A sang trái 1 hàng ta được số B nên số B=\(\frac{1}{10}\)A

Nếu chuyển dấu phẩy của số A sang phải 1 hàng ta được số C nên số C=10A

Ta có A+B+C=221,778

<=> A+\(\frac{1}{10}\)A+10A=221,778

<=> 11,1A=221,778

<=> A=221,778/11,1=19,98

Vậy A=19,98

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.

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

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 = 100 x B + 10 x B = 111 x B = 221,778

B= 1,998 Số A là 19,98

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
