The numerator and denominator of eleven out of seventeen minus one number is four out of seven, which is ()
Let this number be X
11 out of 17 is 11:17
Four out of seven equals four to seven
(11-x)：（17-x）=4:7
4(17-x)=7（11-x）
68-4x=77-7x
3x=9
x=3
A: the cut number is 3

The sum of the numerator and denominator of a fraction is 43. If 17 is added to the denominator, the fraction can be reduced to 13, which is______ ．
43 + 17 = 60, total number of shares: 1 + 3 = 4 (shares), numerator: 60 × 14 = 15, current denominator: 60 × 34 = 45, original denominator: 45-17 = 28, then the original score is 1528

The sum of the numerator and denominator of a fraction is 47. If the numerator plus 17 equals 1, what is the original fraction
15/32
(47 + 17) / 2 = 32 is the denominator
47-32 = 15, 15 is a molecule
