BÀI GIẢI
Vì khi chuyển dấu phẩy ở số A sang bên trái 1 hàng ta
được số B nên số A gấp 10 lần số B . Nếu chuyển dấu phẩy ở số A
sang bên phải 1 hàng ta được số C nên số C gấp 100 lần số B .
Ta có :
A + B + C = 100 x B + B + B x 10 = 221,778
A + B + C = 111 x B = 221,778
=> B = 221,778 : 111 = 1,998
=> Số A là :
1,998 x 10 = 19,98
Vậy số A là 19,98
