Gọi số bé là a và số lớn là b.

=> a+b=568

Theo đề ra thì : 5a=b <=> 50+a=b

=> \(\hept{\begin{cases}a+b=568\\50+a=b\end{cases}}\)=> \(\hept{\begin{cases}a=259\\b=309\end{cases}}\)

Vậy số bé là 259 và số lớn là 309.

Vì viết thêm chữ số 5 vào bên trái số bé ta dc số lớn 

=> số bé là số có 2 chữ số và số lớn là số có 3 chữ số

Gọi số bé là ab thì số lớn là 5ab

Ta có ab + 5ab = 568

ab + 500 + ab = 568 

ab x 2 = 568 - 500

ab x 2= 68

ab = 68 : 2

ab = 34

=> số bé là 34 và số lớn là 534

Đáp số : Số bé : 34

Số lớn : 534

Games and sports are an important part of life. Life would be dull without games. In fact, life itself is a game. I love to play games. Football is my favorite game. Last Sunday, my friend and I went to see a football match. It was played between out college team and the Government college team. It was played on our school ground. Both the teams were in uniforms. Both the teams were equally strong. The referee blew a long whistle. There was a toss. We won the toss. Both the teams took their sides. The match started. For some time, the game was slow. But soon it became very brisk. The ball was changing sides again and again. Our players moved as one man. They put up a good show. Then our captain got a chance. He kicked the ball so hard that it passed right through the goal posts. There were loud cheers from all sides. Our Players were mad with joy. Soon there was the interval. Both the teams were given light refreshment. Sides were changed after the interval. The referee blew the whistle and the match started again. The other team tried hard to equalize. But all their efforts were unsuccessful. The referee blew a long whistle. The match was over. Our team won the match by one goal. The students of our college were beside themselves with joy. The next day was declared a holiday. We came back home happily

My Christmas Holidays:
On my Christmas Holidays I didn’t have any day I didn’t make anything.
On 25th December I went to my grandpa and my grandma’s house to have the Christmas lunch. In the afternoon I went to see “Pastorets”, and in the evening I stayed in my home with my family and we watched the TV.
On 26th December I went to my other grandma’s house for having another Christmas lunch. And in the afetrnoon I went to see “Pastorets again.
In 31st December I went to campelles with my cousin and my aunt, and two other families and we slept two nights in a hotel. In the night we ate the grapes at 00:00, we laughed a lot and we had fun.
In the morning of 5th Jenuary I went to visit the “pageboys” of the kings and in the evening I went with my little cousin to give the letter to the kings of “Orient”.
And on 6th I opened the presents in my house and at my grandmpa’s house and we had lunch, and for dessert we ate the ring-shaped cake of the kings.
I had a very nice Christmas holidays… But there were very short!!!

Christmas is a holiday on December 25th celebrating the birth of Jesus Christ. Christmas has now become more and more popular in VietNam, especially to young people. On this day, people often decorate their houses and prepare presents,... . Even so, many households in big cities buy the Christmas tree and hang lights and small bells upon it. Children also love Christmas day so much. They prepare clean stocks for receiving the presents from the Santa Claus. How about the celebration? On Christmas Eve, people often sing Christmas Carol, meet friends, relatives to make a wish for them. Some people often impersonate Santa Claus and give present to everyone. All Christians go to church on this day. In England and Australia, people often make Christmas cake - a traditional food made for Christmas day. 

I the story of Doremon very much. It is about the friendship between Doremon and a naughty boy called Nobita. Doremon comes from the 22nd century. Its main duty is to help Nobita to get out of trouble.Unfortunately, that happens to Nobita quite a lot.Every time, Doremon uses the amazing tools from its pocket to help Nobita. There is the time-door which can take people anywhere they want to go. Then there is the light beam that can make people or things smaller.Nobita thanks to that, too.But nobita has a good hearted hioeenf that makes friends can not be separated from his friends, so he always makes doraemon help them so I admire their friendship
