When I was in 2nd grade, I used to have a machine pen, but my father said: "When I go to class 4, use it, son!" Then first day in class 4, Dad bought me a plastic pen. The pen is nearly an inch long. Body pen circle, small with index finger. Plastic of pen still fragrant, smooth and shiny. Pink pen cap, silhouette iron hook. When I opened the lid, I saw the shiny pen, the picture of the bamboo leaf, there were a few words very small, I didn't look clearly. Each time of taking the ink, half nib pen with purple ink. I wrote on paper pages, flexible pen strokes created regular lines. After writing, I used the mop to the ink from the safe. After that, I checked the cap of the pen to avoid breaking the stinger before putting in the folder. It was a few months and my pen was still new. Pen and I work hard every day as a farmer plow in the field.

5+4=9 => bạn lớp 9 , đúng ko ??

5+4=9

=> Chủ acc đang học lớp 9

Phân số chỉ 3 học sinh là:

1-1/2-1/4-1/7=3/28(số học sinh)

Số học sinh ở lớp thầy là:

3\(\div\)3/28=28(học sinh)

Đáp số:28 học sinh

Ai tích mình mình tích lai cho

Độ dài \(\frac{1}{5}\) bức tường còn lại là: \(\frac{1}{5}\) . 1,25 = 0,25 (m)

Chiều rộng lớp học là:

4.1,25 + 0,25 = 5.25 (m).

Đáp số: Chiều rộng bức tường dài 5,25 m.

Sau 4 lần căng dây thì chiều rộng lớp học là :

1 , 25 . 4 = 5 ( m )

\(\frac{1}{5}\) độ dài sợi dây là :

1 , 25 . 1 / 5 = 0, 25 ( m )

Chiều rộng lớp học là :

5 + 0 , 25 = 5 , 25 ( m )

Đáp số : 5,25 m

Sau 4 lần căng thì đo được:

1,25 . 4 = 5 (m)

1/5 độ dài sợi dây là:

1,25 : 5 = 0,25

Chiều rộng lớp học là:

5 + 0,25= 5,25 (m)

Đ/S: 5,25 m.

Vậy chiều rộng lớp học là 5,25 m.

Chúc bạn học tốt!
