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

Set the number of oranges to a, the number of apples to b .
Know that a = 3/2 b, a + b = 15
=> a = 15: (3 + 2) x 3 = 9
<=> b = 15 - 9 = 6
So the number of apples is 9, the orange number is 6 .
Apples: +----+----+----+
Oranges: +----+----+
The number of apples is:
15 : (3+2) x 3 = 9 ( apples )
The number of oranges is:
15 - 9 = 6 ( oranges )
Ans: oranges: 6
apples: 9
