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=...

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
