tớ không biết. học dốt lắm

chắc 90

a)công thức: X x 79000=Y

b)Số người đã tham dự buổi tiệc:790000:79000=10 (người)

   Số người bạn của Mai đã tham gia buổi tiệc là:10-1=9 (người)

(giải thích: trừ đi 1 là không tính bạn Mai)

Vì mỗi phần ăn của mỗi người là 79000 nên ta có phép tính như sau : 
       790000:79000=10 người  
                  Đáp số : 10 người

63 người vì 1 tháng 10 có 31 ngày nên chắc chắn có 3 người cùng ngày thì chúng ta lấy 31.2+1=63

Có 97 bạn nữ và 1 bạn nam tham dự bữa tiệc

có 97 bạn nữ có 1 bạn nam

97con trai 1con gái tham dự tiệc

Dear Mai,
I want to make a small announcement that next week is my birthday, and it would be great if you can take your time and join us for a small party at my house. It will be started at 5pm and maybe ended early around 9pm, so I hope it is a suitable time for you and everyone. There will be birthday cake, delicious dishes that are made by my mom, and a lot of candies at the party. We can eat and play a lot of fun games afterwards.
Call me if you cannot make it to my party
I am looking forward to hearing from you soon
Love,
Nha.

Mai thân mến,
Tớ có một thông báo nho nhỏ rằng tuần tới chính là sinh nhật của tớ, và sẽ thật tuyệt nếu cậu có thể dành thời gian để cùng tham gia một bữa tiệc nhỏ tại nhà tớ. Bữa tiệc sẽ được bắt đầu vào lúc 5 giờ chiều và có thể kết thúc sớm vào lúc 9 giờ tối, vậy nên tớ hi vọng đó sẽ là một khung giờ thích hợp cho cậu và tất cả mọi người. Sẽ có bánh sinh nhật, các món ăn ngon do mẹ tớ nấy, và thật nhiều kẹo ở đó. Chúng mình có thể ăn và sau đó chơi các trò chơi vui nhộn.
Hãy gọi cho tớ nếu cậu không thể đến bữa tiệc nhé
Tớ mong nghe tin của cậu sớm
Yêu thương,
Nhã.

\(\text{Có số bạn được mời đến dự sinh nhật của Minh là:}\)

            \(3:\frac{3}{7}=7\left(\text{bạn}\right)\)

                       \(\text{Đáp số: 7 bạn}\)

những người bạn đến dự tiệc là

3:3/7=7(người)

đáp án 7(người)

Số người ăn pizza 

\(3:\frac{3}{7}=7\) ( người ) 

Do có Minh ăn nên số người được mời là 

\(7-1=6\) ( người )

Dear friend,

Do you know next Thursday will be a day of eager anticipation to me? It is then the day before my fourteenth birthday. I have been looking forward to the party for at least two months. Everything is supposed to be perfect for that day: balloons, candles and tasty dishes, and music. There will be a barbeque of magnificent proportions. Miraculously, an enormous ice cream cake will be delivered with eight large pepperoni pizzas. Needless to say, I am excited. It is to be my first party at our new house.

I'm looking forward to seeing you come, that'll bring more life to this special event of mine.

Best wishes,

Thuy Trang
