rồi đó, nhớ **** cho mk nha

Are there any carsin front of the police station.

he always busy because he is businessman.

Gọi 2 số cần tìm là a và b

Ta có:

7/9 . a = 2/8 . b

=>56a=18b =>28a=9b(1)=>b>a

Mà b-a=9

=>9b-9a=9.9=81

Từ (1) =>28a-9a=81

=>19a=81

=>a=81/19

b=81/19 + 9=252/19

Vậy 2 số cần tìm là 81/19 và 252/19

thank you very much for your letter
