Gọi tử số của phấn số cần tìm là x thì mẫu số của phân số cần tìm  là x+11. Phân số cần tìm là \(\frac{x}{x+11}\)( x là số nguyên khác -11)

Khi bớt tử số đi 7 đơn vị và tăng mẫu lên 4 đơn vị ta được phân số

\(\frac{x-7}{x+15}\)(x khác -15)

  theo bài ra ta có phương trình \(\frac{x}{x+11}=\frac{x+15}{x-7}\)

giải phương trình và tìm được x=-5 ( thỏa mãn)

từ đó tìm được phấn số \(-\frac{5}{6}\)
