XI- Write a passage (80 -100 words) about your school.

Số học sinh giỏi toán so với số học sinh giỏi cấp trường chiếm

 \(\dfrac{1}{3}\) ( số học sinh giỏi cấp trường)

Số học sinh giỏi ngoại ngữ so với số học sinh giỏi cấp trường chiếm:

    \(\dfrac{1}{3}\) : \(\dfrac{4}{5}\) = \(\dfrac{5}{12}\) ( số học sinh giỏi cấp trường)

Phân số chỉ 6 học sinh giỏi văn là:

1 - \(\dfrac{1}{3}\) - \(\dfrac{5}{12}\) = \(\dfrac{1}{4}\)( số học sinh giỏi cấp trường)

Số học sinh giỏi cấp trường là

     6 : \(\dfrac{1}{4}\) = 24 ( học sinh) 

số học sinh giỏi toán là: 24 \(\times\) \(\dfrac{1}{3}\) = 8 ( học sinh)

Số học sinh giỏi ngoại ngữ là: 24 \(\times\) \(\dfrac{5}{12}\) = 10 ( học sinh)

Kết luận

Cách hai :

Gọi số học sinh giỏi cấp trường là \(x\)  (học sinh,  \(x\in\) N*)

Số học sinh giỏi toán là: \(x\times\) \(\dfrac{1}{3}\) = \(\dfrac{1}{3}\)\(x\) 

Số học sinh giỏi ngoại ngữ là: \(\dfrac{1}{3}x:\dfrac{4}{5}\) = \(\dfrac{5}{12}\)\(x\)

Theo bài ra ta có:

\(x\) - \(\dfrac{1}{3}x-\dfrac{5}{12}x\)  =  6

\(x\) \(\times\)( 1 - \(\dfrac{1}{3}-\dfrac{5}{12}\)) = 6

\(x\) \(\times\) \(\dfrac{1}{4}\) = 6

\(x\) = 6 \(\times\) 4 = 24

Số học sinh giỏi cấp trường là 24 học sinh

Số học sinh giỏi toán là: 24 \(\times\) \(\dfrac{1}{3}\) = 8 ( học sinh)

Số học sinh giỏi Ngoại ngữ là 24 \(\times\) \(\dfrac{5}{12}\) = 10 ( học sinh)

Kết luận: Số học sinh giỏi cấp trường là: 8 học sinh

               Số học sinh giỏi toán là: 8 học sinh

               Số học sinh giỏi ngoại ngữ là 10 học sinh

              Số học sinh giỏi văn là 6 học sinh
