Bài 1

Một chiếc điện thoại được giảm giá bán hai lần: mỗi lần 10% giá đang bán thì bán với giá 9720000 đồng. Hỏi  giá bán  ban đầu của chiếc điện thoại đó là bao nhiêu.
Giải
Xem giá lần đầu tiên là 100%. Giảm lần thứ nhất 10% thì còn 90%.
Giảm 10% lần 2 thì giảm:  90% x 10% = 9%
9720 000 đồng ứng với:   (100% - 10% - 9%) = 81%
Giá chiệc điện thoại trước khi giảm:
9720 000 : 81x 100= 12 000 000 (đồng)

Bài 2 

Tổng các số lẻ nhỏ hơn 100 là bao nhiêu?
Bài giải
Số lẻ đầu dãy: 1
Số lẻ cuối dãy: 99
Số các số hạng : ( 99- 1) : 2 + 1 = 50 ( số)
Tổng các số lẻ nhỏ hơn 100 là : 
( 1 + 99) x 50 : 2 = 2500
Bài 3

Tổng của A +  B và C là : (432,5  + 368 + 421,5) : 2 =  611
Số B là : 611 – 368  = 243

Bài 4

Chiều rộng bằng 3 phần thì chiều dài bằng 4 phần bằng nhau như thế:
Ta có hình vẽ:

Giá trị một ô vuông nhỏ : 588 : ( 3 x 4)  = 49 cm2 Vậy cạnh hình vuông nhỏ là : 7 cm ( vì 4 x 7 = 49) Chiều dài hình chữ nhật : 7 x 4 = 28 (cm) Chiều rộng hình chữ nhật : 7 x 3 = 21 (cm) Chu vi hình chữ nhật : ( 21 + 28 ) x2 = = 98 (cm)Chiều rộng hình chữ nhật : 7 x 3 = 21 (cm) Chu vi hình chữ nhật : ( 21 + 28 ) x2 = = 98 (cm) 
Bài 5

Bài giải
Quãng đường đi là: 40 x 3 = 120 (km)
Va tốc trung bình của người đó cả đi lẫn về:
(120 x 2 ) : ( 3 +2) = 48 (km/giờ)

I have a big family which gives me everything that I need. My parents have two children, and we also live with our grandparents. Both of my parents have to work very hard to support this family, so they rarely have time to play with us. I am now a grown up boy, so I take the responsibility to take care of my little sister and grandparents when my parents are not home. My father is a manager of a Sell Apartment, and my mother works at the bank. They both have medium height and black hair, and they are very hard - working employees. They usually leave early in the morning without having breakfast at home, and my grandmother is the one who cooks for me and my sister. Both of them are just 75 and very healthy, they have grey hair and some wrinkles as well as freckles on their faces. They spend their free time to play with my sister whenever I go to school. I travel to school by bike, and I am a pretty good student. When I am home, I help doing the house chores, help my grandmother preparing the meals, and look after the baby. My hobbies are playing sports, but I only go out and play with my friends when both of my parents are at home at the weekends. My favorite time of the day is dinner time, because the whole family will all gather after a long day staying out. We spend that little time to talk about our days and share funny stories. Although my parents do not have much time for us, I still love and be thankful to have such a great family that.
