Tính theo tử số:
Tử số bé nhất là 0,tử số lớn nhất là 2009(Vì nếu tử số bằng 2010 thì mẫu số bằng 0 hay số chia bằng 0,vô lí)
Có tất cả:
(2009 - 0) :1 + 1=2010 (phân số)
Tính theo mẫu số:
Mẫu số bé nhất là 1(mẫu số khác 0); mẫu số lớn nhất là 2010
Có tất cả :
(2010 -1) : 1 + 1= 2010 (phân số)

My first visit to Nha Trang, the coastal city, was three years ago. It was a pleasant and memorable trip.

Nha trang, the capital of Khanh Hoa province, has one of the most popular municipal beaches in all of Viet nam. In Nha Trang, nature beauties are so tempting. Waves crashing onto the cliffs, the soft sigh of the sea breeze, clean white sands and turquoise waters, it all makes for a stunning landscape. On my visit to Nha Trang, I used to get up early each morning to stroll along the beach - a chance to breath in the fresh sea air and enjoy the sunrise across the water. One attraction that captivated me three years ago and still it does is the collection of small offshore islands, that is Hon Tre where is the largest of the islands.

Nha Trang is the city in hamoney, its fine wather, favorite position and friendly people bring it a certain balance. Nha Trang is a great holiday destination. I hope to have chance to come back

Tôi đến thăm Nha Trang, thành phố biển, lần đầu cách đây ba năm. Đó là một chuyến đi thú vị và đáng nhớ

Nha Trang, thủ đô của tình Khánh Hòa, có bãi biển đẹp nhất trong số các bãi tắm trong thành phố trên toàn Việt Nam. Ở Nha Trang, thiên nhiên thật quyến rũ. Sóng xô bờ đá, hơi thở nhẹ nhàng của gió biển, bãi cát trắng và nước biển trong xanh, tất cả đã tạo nên phong cảnh tuyệt vời. Trong dịp đi thăm Nha Trang hồi đó, tôi thường dậy sớm vào buổi sáng đi tản bộ dọc theo bờ biển - một dịp để hít thở không khí biển trong lành và thưởng thức cảnh bình minh trên biển. Một nơi hấp dẫn đã lôi cuốn tôi cách đây ba năm và bây giờ vẫn thế là tập hợp những hòn đảo nhỏ xa bờ. Đó là Hòn Tre, một hòn đảo lớn nhất

Nha Trang là thành phố của sự hài hòa, thời tiết đẹp, vị trí thuận lợi và người dân thân thiện đem lại cho Nha Trang sự cân bằng vững chắc. Nha Trang là điểm dừng chân du lịch lý tưởng. Tôi hi vọng có cơ hội trở lại.

Last summer, I went to Cua lo with my family. We went there by car, it is very far from my house, it is about 400 km, so we were very tired, but at one we felt better when we saw the sea.

Cua lo beach is really interesting, the beach is very large, flat, and it has a lot of sand. Waves are very strong, you will be very excited when you play with it. There are a lot of beauty spots, and good seafood there

We stayed in Binh Minh hotel. It was a very nice and comfortable hotel, it’s also rather near the sea.

The weather was hot and sunny all day. The sea was cool and clear, because it was very windy in the afternoon. We went swimming twice a day. My children was excited about it. The food was extremely delicious but not very expensive.

We took a lot of Photograps of the sea, bought a lot of seafood especially octopus and some sea present for our relatives.

After a week in Cua lo beach we felt happy and stronger.

We hope to go there again.

Hanoi has Sword Lake
Blue water like ink
I often remember the familiar verse when it came to Ho Guom. Hoan Kiem Lake is located in the heart of Hanoi Capital. The lake is as green as a giant carpet. In the middle of the lake, on the green grass is the ancient turtle tower, glass. In the far distance, the Huc Son bridge was curved like a shrimp leading tourists to visit Ngoc Son temple. The ancient moss house is located next to the old root. In the temple there is a large turtle displayed in a large glass cabinet. Looking at this tortoise reminds me of the Ho Guom Lake. King Le Loi returned to seek Kim Quy god on Ta Vong lake or Hoan Kiem lake. When the summer, the tune mingle with the bird to create a concert that lasts forever. Along the way, the willow balls leaned down to glimpse into the lake like the long hair of the girls down to coast.On the festive days, the lake shimmering by thousands of colored lights, the milk flowers radiate aroma soothing softly to the shoulders of passers. I have not forgotten about Ho Guom - a beautiful landscape - was attached to me throughout my childhood.

\(\frac{3}{x-5}=-\frac{4}{x+2}\)

\(\Rightarrow3x+6=-4x+20\)

\(\Rightarrow7x=14\)

\(\Rightarrow x=2\)

\(\frac{3}{x-5}=\frac{-4}{x+2}\)

\(\Rightarrow3\left(x+2\right)=-4\left(x-5\right)\)

\(\Leftrightarrow3x+6=-4x+20\)

\(\Leftrightarrow7x=14\)

\(\Leftrightarrow x=2\)

\(\frac{3}{x-5}=\frac{-4}{x+2}\)

<=> \(3\left(x+2\right)=\left(x-5\right)\cdot\left(-4\right)\)

<=> \(3x+6=-4x+20\)

<=> \(3x+4x=20-6\)

<=> \(7x=14\)

<=> \(x=2\)

hình như là =9cm

Vì D là trung điểm của AB 

=> AD = DB = AB : 2 = 10 : 2 = 5 (cm)

Lại thấy BC + DB = CD (vì chúng nằm trên một đường thẳng)

Thay BC = 4 cm ; DB =  5 cm, ta có :

CD = 4 + 5 = 9 (cm) 

Vậy CD dài 9 cm.

Chúc bn hok tốt ! mk nha !
