The numerator of a fraction is 14 smaller than the denominator. If the denominator is added with 4, it can be reduced to 13. The original fraction is______ ．

Let the denominator be X. according to the meaning of the question, & nbsp; & nbsp; X − 14x + 4 = 13, (x-14) × 3 = x + 4, 3x-14 × 3 = x + 4, 3x-42-x = x + 4-x, 2x-42 + 42 = 4 + 42, & nbsp; & nbsp; & nbsp; & nbsp; 2x = 46, & nbsp; 2x △ 2 = 46 △ 2, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 23, the molecule is

The numerator of a fraction is 17 smaller than the denominator. If the denominator is added with 7, it will be divided into about 1 / 4. What is the original fraction

8 / 27 let the numerator be x and the denominator be y
Y-X=17
X/(Y+7)=1/4
The simultaneous equations, x = 8, y = 25

The denominator of 11 / 17 minus the same number is 4 / 7. What's the number?
Find the formula

3

If you subtract a number from the numerator and denominator of 11 out of 17, you will get 4 out of 7?

(11-x)/(17-x)=4/7
77-7x=68-4x
x=3
