Currently, there are many students who can't concentrate at school when they come to school, so what is the cause of this problem and how to solve it. The main reason comes from the fact that they only pay attention to the TV or the phone, or the game because they often only focus on the phone and neglect their studies. The second reason may be that the pressure of the family makes the children think about family matters. The third reason is that children may be tired but their parents still force them to study hard. The fourth reason is that children are pressured by their parents about their studies, making them overly forced. So what's the solution ? Every parent should give their children a comfortable entertainment space so that they have a spirit of readiness to study so that their minds are more comfortable to focus on studying.

The reasons that I give are not necessarily correct, but I will have my own reasons: Students often talk during the hours when the teacher is giving a lecture, causing the teachers to have a headache, tired of the students telling you to "shut up", or teasing you, hitting you to cover up for each other. tell the teacher to solve it for fairness, there are times when not paying attention to the lecture. And these are the problems that I will handle in the above cases: We should know that teachers take care of each student like parents, so we have to be good to not talk to make teachers headache, tired, shouldn't tease you, maybe you can get hurt, we should not cover for you maybe you will lose and we have to concentrate or we won't remember the knowledge Here are my reasons and solutions, I hope you and your brothers and sisters will agree.

I am an organizer of the Maths-English contest, so of course I'd love to answer these topics!

Calling the number of apples the sister left for her brothers x [apple(s), \(x\in N\)*].

With the first statement related to the question, the oldest brother divided the apples into three parts, leaving an apple to the youngest one. So the number of apples left for the two younger brothers is: \(\dfrac{x}{3}+\left(\dfrac{x}{3}+1\right)=\dfrac{2x+3}{3}\).

With the second statement, the middle brother divided the apples into three thirds and gave away one apple in his ration. So therefore, the number of apples left for the youngest brother is: \(\dfrac{\dfrac{2x+3}{3}}{3}+\left(\dfrac{\dfrac{2x+3}{3}}{3}+1\right)=2.\dfrac{2x+3}{9}+1=\dfrac{4x+6}{9}+1=\dfrac{4x+15}{9}\).

With the third statement, the youngest brother woke up and saw 7 apples. So we have:

\(\dfrac{4x+15}{9}=7\)

\(\Leftrightarrow4x+15=63\).

\(\Leftrightarrow4x=48\).

\(\Leftrightarrow x=12\). This answer satisfies the conditions of x.

Thanks everyone for your interest to this answer. And don't forget, the Vietnam English-Maths Contest hosted by me and VICE members will begin in the 29th of June, 2021 ^^

úi, idollllll :v

em có vò cái link danh sách nhưng ko đc thế là lại phải vào lại cái vòng 1 đếm 30 đứa đầu tiên^{(tự nhiên thấy mình,cứ tưởng ko đc đi tiếp)}

à em sai chinhs tả chút:vò = vào ạ(đánh máy hơi vội)

Gòi nhận GP kiểu chi, mà ko thi vòng 2 nữa đc ko, thất vọng ghê á

với lại cho mình ý kiến chút, đó là đề bài để hơi nhỏ gây khó khăn cho việc quan sát, cùng với việc là lúc ban đầu khi hệ thông lỗi mà mình có thể nhìn đc bài người khác nên có thể là có vài thí sinh sẽ đc vào vòng 2 bằng cách này

Không sao, 23h59' nộp vẫn còn kịp :v

Mà nhớ canh kĩ nha qua 0h00 thì có 100 điểm cũng k nhận đou :v

sao em lại chỉ có 13đ nhỉ^(sốc)

Today, there are many parents who are indifferent to that child doing a very harmful job. Today's era develops and people also develop with the times. Parents often think that having a lot of money will lead to a happy life. Should only pay attention to making money and neglect to care for children. Some people even think that their job is right because they earn money to support their children. But I don't know that behind there are many consequences. For example, my child's school failure is not known, or he learns bad habits or he does not eat enough nutrients.. mother cares. and there are many others as well. From those consequences, each parent needs to spend a little of their time taking care of and re-teaching their children more.

      Today, parents spend less time with their children than in the past. Many parents meet all material requirements such as TVs, computers, and phones for their children to help their children develop comprehensively. However, children do not need those souless things, what children need most of all is the care and spiritual support of their parents at the right time. Talking to children every day, prompting them to confide in their parents sometimes only takes an hour. When spending time with children, what they need is comfort, encouragement, sharing, not blame or scolding. If so, then children will be the most affected and hurt. Children who lack family affection become indifferent, emotionless, do not care about others, are under a lot of pressure in life, are ridiculed by friends. Therefore, in any era, parents should pay attention and spend more time with their children, do not let them become insensitive.

      I think there is one person who deserves to be the leader, that is Quoc Anh. With enthusiasm for the Hoc24 website, he has a lot of experience and is trusted by teachers to assign many important tasks. He is so enthusiastic that at 12 o'clock at night he still works for Hoc24. That is a shining example for us to follow! He also gets along very well with the other members, not alienating or feeling inferior to them. I admire his talent and determination and I hope he becomes a great leader.

In my opinion, a good leader is someone who:

+ Speak can be done.

+ Listen to the people around you.

+ No discrimination. 

+ Know how to plan.

+ Know how to inspire people around.
