Gọi phân số cần tìm là x
Theo bài ra ta có: 3/2-x+5/7=11/14
3/2-x =11/14-5/7
3/2-x = 1/14
x = 3/2-1/14
x = 10/7
Vậy: x= 10/7
Goi phan so can tim la x
Theo bai da ta co :
3/2-x+5/7=11/14
3/2-x=11/14-5/7
3/2-x=1/14
x=3/2-1/14
x=10/7
Ta gọi số cần tìm là x
3/2-x+5/7=11/14
3/2-x=11/14-5/7
3/2-x=1/14
x=3/2-1/14
x=10/7
Ta có : 11/14 - 5/7 =1/14
=3/2 - 1/14
=20/14
