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

I have a best friend named Linh, we have been together since we were just little kids. She has beautiful bright skin and brown eyes. We have a lot of things in common, such as we love the same band, food and books. She and I even share the same name, and it is a small surprise for anyone who has talked to us. Linh is not my classmate, but we always help each other with the homework and school projects. We spend every minute in our break time to talk about all the things that happen in class, and people usually ask what can even makes us laugh that hard. Sometimes I think it is we have been best mates since forever, and I hope that we will be happy this for a very long time.

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
Lan và Bình gặp nhau lúc 8 giờ sáng hôm nay.
Giả sử Lan và Bình gặp nhau lúc \(t\) giờ. Theo đề bài, khoảng thời gian từ 0 giờ đến lúc gặp nhau là \(t\), và từ lúc gặp nhau đến 24 giờ là \(24 - t\), và ta có phương trình \(t = \frac{1}{2} \left(\right. 24 - t \left.\right)\). Giải phương trình này, ta tìm được \(t = 8\), vậy Lan và Bình gặp nhau lúc 8 giờ sáng hôm nay.
