51/85 = 3/5
Hiệu số phần bằng nhau là 5-3=2(phần)
Tử số là 52:2x3=78
Mẫu số là 78+52=130
Phân số là 78/130
có phải: (tìm phân số bằng phân số 7/10 mà tử số nhỏ hơn mẫu số 2004 đơn vị ) ko?
Yes(vâng)

Hiệu số phần bằng nhau là: 10 - 7 = 3 (phần)
Giá trị 1 phần là: 2004 : 3 = 668
Mẫu số là: 668 x 10 = 6680
Tử số là: 668 x 7 = 4676
Vậy phân số đó là \(\frac{4676}{6680}\)
4676/6680
4676/6680
