8/7 nha!

\(2000:1750=\frac{2000}{1750}=\frac{2000:250}{1750:250}=\frac{8}{7}\)

  ( phân này lớn hơn bạn có thể viết dưới dạng hỗn số đấy = \(1\frac{1}{7}\))

Cái này chắc là đề THCS chứ không phải toán lớp 2 bạn à. !! >_<

Almost people say that they prefer living in the peaceful countryside to the noisy city. I agree with them but I can't admit it when I live here-my second hometown-Tay Ninh. Although Tay Ninh is now a city but it's very peaceful and comfortable. I can hardly hear any loud noise and you know, to me, the most peaceful place is my neighborhood.

My family and my neighbors live together on Dien Bien Phu Street. Every morning when I get up, I always can see the sun shining and there are some warm voices from the small beautiful birds and the sounds from my neighborhood. We all get up very early. A new day begins. I often wander around my neighborhood. There are lots of green trees along the streets. There, we can see a range of houses from high to short, ordinary to extraordinary. We all do business. Some neighbors sell foods, drinks and household appliances as grocery stores. Some are tailors who mend clothes, make clothes and mend shoes too. Some are the barbers who cut hair and give make up my mother. Some are bakers who bake cakes in the bakery and sell breads. The environment is never polluted and we can feel the warm atmosphere everytime.

All the inhabitants in my neighbor are very friendly to each other. Whenever a person needs help, the others are always ready to give help and one thing should be mostly appreciated is that they never mind how difficult the work is. And we build such a great consolidation. When a neighbor has just returned from a trip, they always remember to buy the others some beautiful and worthy gifts and we also share the money for parties together. We never underestimate the honor we give each other.

I love my neighborhood very much. I hope that our friendliness and consolidation will last forever and remain unchanged.

Sao đề lạ thế hai Bt cùng giá trị sao làm được

ừ nó v đấy chép nguyên văn luôn

Vì \(x-2\) và \(2-x\) đối nhau \(\Rightarrow\left|x-2\right|=\left|2-x\right|\)

\(\Rightarrow\left|x-2\right|+\left|2-x\right|=2\left|x-2\right|\)

\(\Rightarrow2\left|x-2\right|=10\)

\(\Rightarrow\left|x-2\right|=5\)

TH1 : \(x\ge2\) ta có :

\(x-2=5\Rightarrow x=7\) (TM)

TH2 : \(x< 2\) ta có :

\(2-x=5\Rightarrow x=-3\)(TM)

Vậy x = 7 hoặc x = - 3

Diện tích miệng giếng là :

0,7 x 0,7 x 3,14 = 1,5386 (m²)

Bán kính giếng là :

0,7 + 0,3 = 1 (m)

Diện tích thành giếng là :

1 x 1 x 3,14 = 1,6014 (m²)

ĐS : 1,6014 m^kj

Diện tích miệng giếng là : 0,7 x 0,7 x 3,14 = 1,5386 ( m² )

Bán kính hình tròn lớn là : 0,7 + 0,3 = 1 ( m )

Diện tích hình tròn lớn là : 1 x 1 x 3,14 = 3,14 ( cm² )

Diện tích thành giếng là : 3,14 - 1,5386 = 1,6014 ( cm² )

2kg 45 g = 2,045 g

1 yến 2 kg = 1,2 yến
