I think that hobby is important thing in our

life. At the moment we have a lot of hobbies which are very modern and popular. For example photography, theatre, reading, collecting marks or doing videos. It seems to me that hobby is the greatest thing in people’s life.
Let’s start with my hobby. My hobby is cooking. I love to cook and experiment with some products. It’s very funny and exacting. In my opinion, a lot of people like cooking but a little people do it as a hobby, because you must have a talent. Another advantage of cooking is that you must not do everything that is written in cookery books. On the other hand, cooking is a very good hobby, because you use a lot of qualified products and there are no chemicals.
It seems to me that having such a hobby at my age cooking is very good, as it will be an advantage in future for me, because I will cook qualified and healthy food for my husband and children. And nowadays I know what I will cook for my family.
To sum up, I believe that everyone needs some hobby to relax and in order not to waste time on unimportant and unnecessary things.

I have many hobbies, such as, playing football, game online and swimming. However, my favourite one is reading manga, a kind of Japanese picturebooks. Whenever i have spare time, i would like to lie on my bed and enjoy thrilling and interesting adventures described through beautiful pictures. Moreover, reading these books makes me feel comfortable and relaxed after a hard-working day in my university.Finally, sometimes, they make me think about life's lessons of love, friendship and family by touching stories , which is the main reason why i like this kind of books.

Bài đầu mk cóp trên google đó!

Ta thấy : A = 1 - 1/2 + 1/3 - 1/4 +...+ 1/99 +1/100

             A = 1 + 1/2 + 1/3 + 1/4 +...+ 1/99 + 1/100 - 2. (1/2 + 1/4 +1/6 +...+ 1/100)

            A = 1 + 1/2 + 1/3 +1/4 +...+ 1/99 + 1/100 - (1 + 1/2 + 1/3 +...+1/50)

            A = 1/51 + 1/52 + 1/53 +...+ 1/100

Do đó : A = (1/51 + 1/52 + 1/53 +...+ 1/75) + (1/76 + 1/77 +...+ 1/100)

Ta có : 1/51 > 1/52 > ... > 1/75    ;     1/76 > 1/77 > ... > 1/100 nên :

           A > 1/75.25 + 1/100.25 = 1/3 + 1/4 = 7/12

           A < 1/51.25 < 1/50.25 + 1/75.25 = 1/2 +1/3 = 5/6

Vậy 7/12 < A <5/6 . ^_^
